That's just some peoples opinion. I don't think it works like that. Have you ever given it 30% gas off a stop. It will see the lag.

 

It can cause more wear and tear on the motor not to mention you fuel consumption with increase too. That's why I sold mine and the jerky throttle too

 

I bought a pinto because i care about fuel. Oh wait i bought a Crossfire because i didn't care.

 

Ok, you guys understand ... The Sprint Booster only provides a "TWITCHIER" throttle response... No HP increase, just a quicker (milliseconds) response to your foot on the throttle... It takes some getting used to... I couldn't use mine anymore because it prevented smooth feathering of the throttle thru very high speed turns on the track... It was too "HERKY JERKY"...

It's really great for the quick-off-the-line type of driving...

 

Yup...It confirms what I thought...I think I'll spend the $300 bucks on gas and drive like an animal on the expressway up north this weekend! I shaved a half hour off a 2 hour drive last weekend on I-75!! DAMN... I love this car!!!

 

Seriously, its not worth the money, but if you have to drop $300 bux get the SI ecu upgrade for $600, that's 20 hp right there. Personally I would rather spend $1,500 on a stand alone ecu and program my own maps. The car is still very new and the aftermarket has yet to catch up. Just be patient.

 

I purchased my sprint booster online, $245 shipped, I received it in less than a week. Should anyone be interested, you can check it out.

This is one of the best mods IMO.

 

Where did you get it?

 

click the link, that press pay it paypal button for the model you want.

 

Even if you have the 20 hp tune, it still won't fix the throttle lag.

 

And a BIG thank you to you too.

Mine arrived yesterday, had to pick it up at the Post Office today, because I didn't want to wait for them to try to deliver it again.

I purchased it from the dude in Hong Kong that is selling them on Ebay. No troubles, quick email return to my inquiry and it arrived express mail in a timely manner even though it was Memorial Day weekend.

Anyways... though I am mechanically inclined, this "15 minute" job took me over 2 hours. I was ready to destroy anything and everything in sight do to anger/frustration...

It was that damn washer... that little #^#$$%!! helper washer!

I didn't have a magnet.... couldn't get it with a variety of grabby tools I had... went to the auto parts store and they didn't have a periscope magnet tool that was small enough... Grrrr... I ended up calling my regular mechanic to see if I could borrow a tool.

I'm telling you, I was ready to get some super glue and a little stick out of the yard. I was P*SSED.

Mechanic to the rescue. (My non warranty work for my Xfire and my little truck I take to my mechanic. I haven't had the Xfire in for anything yet... though I'll probably buy my next set of tires from them... just because).

This is yet another lesson on why "I" don't work on cars.

Ok.. wing mode off.

As for performance, it is nicely noticeable UNLESS I really lay into the accelerator. There is still some hesitation if I floor it, but aggressive acceleration without stomping the gas is much much better. Not worth $300 to me, but I won't be sending it back either.

Now if there were some way to get the autostick to be quicker to respond...

I love this forum.

 

I couldn't get mine with a magnet either. I put 2 drops of super glue on the end of a socket and pushed it over and let it set then it come out.

 

I installed my Sprint Booster on my '04 Crossfire Coupe today and all I can say is WOW !! I have read a lot about these here on the forum and it is by far the best mod for the money so far. Thanks to all here for your opinions and comments regarding these sprint boosters.

 

I am not to knowledgeable about the workings of the onboard computers in cars, but wouldn't adjusting the shift response of the autostick just involve changing some settings in the computer or is that still mechanically limited?

 

can someone send me a link of where i can read about the sprint booster, and how much does it cost?

 

Here is the link to a store on ebay that sells our Sprint Boosters.He is very good as a seller on Ebay. I had mine in less than a week.
Be sure to specify Auto or Manual Transmission. As far as reading about Sprint Boosters the best source of info is right here in this forum.
I recommend it highly for added performance.

Hello,

very long thread, don't know if already someone has mention it : For AMG-Engines (with auto-tranny) like the SRT-6, there is a special Version of the Sprintbooster : BDD451 A2. It is less aggressive because of the extra-Power the AMG-Engine has got...

Sprint Booster Power Converters - What do they do ??

All Engines Chrysler Crossfire

Do you want responsive acceleration, quicker gear changes, and overtake with ease?
This is the answer....Sprint Booster Power Converter...
Sprint Booster is a device that improves acceleration by continuously measuring and converting the digital signal providing the ECM (Electronic Control Module) with a new and altered signal.

Benefits:
 At low revs, the engine responds at approximately half the time in comparison to before.
 The delay time while accelerating in 3rd and 4th gear and the engine in the mid-range, is almost zero.
 Big differences in the higher rev range.
 Improved response for downshifts and safer overtaking.

Almost all new cars come with fly by wire technology; hence do not have a traditional accelerator cable.
This new type of technology has a big draw back; it has a delayed reaction time and hence needlessly delays acceleration and engine performance.
The really great thing about this product is its simplicity; it does not touch the engine at all or the engine management system. What it does do is speed the signal up from the accelerator pedal to the engine - hence greatly improving acceleration and responsiveness!
Sprint Booster is a small and simple unit, which is very easy to install! - It is simply plugged into the back of the accelerator pedal connection and it is only possible to fit the unit one way!

“The Sprint Booster will be the “smartest” gadget you will fit to your car”.

 

Number 1... I've never heard (even from the manufacturer) that the Sprint Booster is a 'Sprint Booster Power Converter'. It simply remaps the accelerator pedal signal curve. This was tested by our wonderful Woody across the pond.

The only reason this affects the transmission in any way is because it's like stomping your foot down quicker.

And... yes, I HATE sales pitches.
