No I haven't, nor do I intend to. It's going to improve throttle response that I have absolutely no issue with? It's somehow going to improve something that doesn't need improving? I know how to push the gas pedal open as slowly or as quickly as I want or need to. Sorry if the words are too big.
I have never, not once, experienced "delayed throttle response"or "hesitation" that others say they have, and, had those issues rectified by a Sprint Booster. I know what the device does. It opens the throttle plate more for a given pedal input. I know how to achieve the same result with my own foot and reflexes.

 

Good for you.... Then you have no problem.... So, your point is, or do you just like to argue? I have a spouse for that. Unless you have a one of kind, there is a hesitation as it is built into the programming of the car. That is fact, not fiction. But, I am glad yours is good for you. But, that isn't case in the other 99.9% on here.

 

You say that "there is a hesitation as it is built into the programming of the car." That is a complete falsehood, a non factual statement. The correlation between the pedal input and the throttle blade opening on a stock car and a Sprint boosted car are indeed different. I know that. Saying there is a built in hesitation is simply not true. I know what a hesitation is, what it feels like (in any car) and it would be quite annoying. Though unlikely, maybe my car is somehow, magically, one of a kind because I have never had any issues with this alleged "hesitation".

 

Sort of makes you wonder why a lot of Crossfires have this hesitation? It doesn't matter, my selectable sprint booster took care of it. Problem solved. The tune was icing on the cake. No one can tell me any different. Best two investments I made on my Crossfire.

 

Let me tell you something pal. I don't get on here and lie. It is throttle by wire. The throttle doesn't open all the way when you place your foot to the floor but opens gradually. Although milliseconds, it isn't instant. That is all the sprint booster does is change to a full throttle response when you step on the pedal. So the liar is you. Anytime anywhere my friend. I am in Michigan a lot. You have called me out. I know what I am stating is fact. I have talked in person with the engineers while at the Woodward Dream cruise. All you want to do at this point is fight....so let's you and I do just that and let this thread be what it is. Which is fact, not you wanting to fight with me. You and I can do that in person, not on a damn computer Rambo.

 

I didn't call you a liar, many people hold beliefs that are not factual. On a variety of subjects, not just things automotive. You need to brush up on your comprehension skills. You are not telling me anything about how drive by wire works, I know what you are saying. Stating that there is a built in hesitation is not true, plain and simple. As you say the Sprint booster opens the throttle more quickly, than does the EO calibration. Still saying there is a built in hesitation is not a statement of fact. Talk to whoever you want to, the OE calibration of the throttle opening is more sedate than a Sprint booster but a built in hesitation is simply not there.
You sound a bit mental but if you want to throw down in cars, at a drag strip, road course, etc I would be game. I have a 05 Crossfire Limited, stock except for Koni shocks.

I'll gladly blow your doors off. Repeatedly.

 

time and place sonny.....time and place.... You can only at this point run your mouth.... You not only called me a liar but everyone on this forum that experiences the same lag. They are not all wrong. You want to argue, start crap on a computer. Name the place and pick either car, hell I will bring them both. It is time some of you that want to talk crap on here put up or shut up. You are in dream land sonny....I'm looking up Clinton and the nearest track now.... Let's do this....
I'm in Adrian area a lot, and I am sure Rob has a track in his area he would recommend. Now I know where to look when I run thru Jonesville on east...

 

Make that a lot mental. And quit calling me sonny, oldtimer. Again I'm not calling you a liar, you just don't know what the hell you are talking about in this case. Who said everyone has this fantom lag? You did. I'm taking that with a grain of salt. make that a pound of salt. I see you have 2 SRT's, maybe they have this lag. Mine is a Limited, I've never experienced any lag or hesitation, ever, not once. If you're in Adrian a lot you should pick up some taco's.

 

Ok I am an ase certified technican for what that is worth.
I had a limited that I did injectors on, Intake and a tune done.
I added a sprint booster. The results were good. The throttle was definitely more responsive.
I did notice a lag and it was gone with the sprintbooster.
I then bought an srt6 off a forum member that ran a 11.8 1/4 mile.
The throttle felt sluggish compared to my limited.
Obviously the srt6 is much faster. We are just talking about throttle response.
I put the sprint booster in the srt and the throttle response was instantly improved.
I do not believe it would make one bit of time difference in the 1/4 however on a road course the lag reduction would help in some scenarios coming off a turn,ect.

 

stryfox, he just wants to be right. And sonny, I am an old timer....and I know a hell of lot more than you. Either put up or shut up. This thread is about lag in the throttle not your limited or what you think. You stated your position and that is good you have a car you are satisfied with. But, others do not. The sprint booster works, and it has many more satisfied users than those who don't like it for what ever the reason. You made it personal, so I will be glad to settle it in person. After all, I'm just an ole' short fat bald guy. What could happen? Or, we can see if you can blow the doors off my slow cars....that would be fun too. You haven't had any constructive thing to say here. None. But I will certainly keep my eye out for that fast limited when passing thru your area...that you can count on. Love to make new friends...sonny. Now let the rest of these car owners have a discussion...we can take it outside....

 

Being an ASE certified technician is worth something. I respect that.
I'm not an ASE certified technician but I'm not some uninformed dufus spouting crap, I completely understand how the Sprint booster works and what it does.
I agree that if I installed a Sprint Booster the interface between pedal and throttle blade would be different, more responsive.
I know what throttle response is and what it should be, how a car should feel. I also know what a hesitation or lag is in a Crossfire or other car. It's an annoying drivability issue that people take cars into a dealerships or independent shops to get fixed quite often.
My car does not have any built in hesitation or lag. It does not have any hesitation or lag attributable to wear and tear conditions or non maintenance or the like.
My has just over 40,000 miles on, and is a well maintained Spring-Summer-Fall only car. It has summer (3 season tires) It will be in the garage in just a few weeks.

Why did you do injectors on the car?, it must have pretty high mileage to actually need new injectors. I'm sure the results were good if you did injectors, intake (which I'm assuming is a CAI to replace the engine top box) and tune done all at the same time.
You also have no evidence proving which of the components or the tune, cured any legitimate drivability issue that may have been present on the car initially.
We can assume it was the Sprint Booster.

 

First things first , you don't know **** more than I do but you're certainly free to think you do.
You're right, it's about "lag in the throttle" or "hesitation" which you say is built in. I say that's a bunch of bullshit.
I've never said the Sprint Booster doesn't work and I'm sure people that have it like it.
You have modified SRT's, I have a stock Limited, you'd win any drag race easily. Or you should.
On a road course you should win also. Probably not though. I doubt you possess the skill set or have any experience at such a venue.
The performance driving season is pretty much over for this year in the northern states. Even good summer tires are not designed to work below 40F, though I'm sure you knew that. The daytime high here yesterday was 48F. Though I have done some open track events (on lucky sunny days) in October in years past. I'd be more than happy to show up at an open track day event next season to see you scratching your head trying to figure out how a Limited could go around a road course faster than an SRT. Have a good day.

 

I'm sorry, I should have been more specific.
When typing on my phone I tend to leave things out because I hate typing on my phone.
The limited crossfire only had about 4000 miles on it when I put larger injectors in.
Anthony of Tvt? Installed a tune for me.
I did not do the Sprint booster at the same time.
It was done separately so I do know the advantage that it made.
If we were discussing a carburetor, at analogy would be kind of like putting a shorter arm on the fulcrum at the carb .
It seems to me with the Sprint booster when the throttle is pushed it sends higher voltage quicker to get this butterfly open sooner.
I am not trying to argue with anyone, just adding some information, for those who read all this stuff. LOL

 

Understood. I'm sure the Sprint booster made a difference. The carb are analogy is right on. That is my understanding of how the Sprint booster works, exactly. Still the OEM ECU has no built in "hesitation" or "lag" as others claim. It is simply a more sedate throttle opening calibration.

 

Sonny, any time any place..... hesitation, lag, delayed throttle response, and now you backtrack with this bullshit..... You are a piece of work. I'm not going any where, you let me know where and when.... I will be there.... But don't steer people wrong on what a sprint booster does. You have managed to talk around what you started out saying. So now the sprint booster does work according to you. I have dealt with politicians who talk around a subject, but you take the cake, sonny. You have a nice winter, I will see you next spring.

 

Listen here Cher . . . and listen good. Or read this again. Either way. And quit calling me Sonny.
I'm not backtracking though maybe you should. Go back and read what I've said earlier you dolt. Your keyboarding hands are writing checks that your brain can't cash. Maybe the Ethyl you've been pumping all their years has addled your gray matter. Something has.

Your as confused as a blind lesbian in a fish market. Try to edit your responses of unnecessary material before attempting to impress us with your insight. The evidence that you are a nincompoop will still be available to readers, but they will be able to access it ever so much more rapidly.

Did you for forget where you said that "there is a hesitation as it is built into the programming of the car.", and I said "That is a complete falsehood, a non factual statement." I also said "Stating that there is a built in hesitation is not true, plain and simple"? well you should, I remember it and it still applies. Do you work for or sell Sprint Booster? I ain't steering no folks wrong neither old-timer. As Jack Nicholson said: "you can't handle the truth".
I never said it does not do something, it does something that you don't have a good understanding of.

I'm no politician though I do like cake. Actually it won't be "any time any place." It will be someplace, but not someplace west of the Mississippi or Alaska for instance.
And you say you're not going anywhere?
How will that work, those are opposites and you just said them? Look up Cognitive dissonance.

Until spring keep in mind that your still going get crushed like a bag of circus peanuts.
Try to form a good mental image of that, or look it up online. It will keep you stoked.

 

 

Maybe his Crossfire has a Sprint Booster and he doesn't know it. Did he get the car used? Did he look to see if it has one? They are not visible without looking.

 

Mental....read your own dribble... It is in the programming retard. Sprint booster does get rid of the hesitation. You may not like to hear that, but they do. I will be in Michigan anytime you want to settle what ever your little feeble mind wants to do, physical or track. Now take your **** some where else. I am tired of reading your bullshit keyboard Rambo talk. In person or walk....no one wants to hear your crap anymore. Especially me....Sonny....

 

DING!!!!!!!! Round 2. I don't have a Sprint Booster in my SRT6 but I know what you are talking about, seems like just a momentary lag between pushing the pedal and engines response, so a SB is probably in my future. And while I'm not taking sides, just stating facts, anyone who thinks his N/A is going to smoke an SRT6 is delusional. Also, I agree that a SB is not going to affect the 1/4 as I am well into the 11's.
