Which should I do first?? Any expertise or advice is welcome!!

Thanks guys

 

I did both and I'm happy with my car's performance. I did the sprint booster first.
The sprint booster gets rid of the throttle lag and the tune improves performance.

 

If you have an SRT I say F' the sprint booster and get the Eurocharged tune.

 

Guy's I have the Eurocharged tune, and there is NO throttle lag, so it would seem the Sprint booster is a waste of money, IF you're going to get a tune ..............JMHO

 

I was wondering the same. I asked the question in another thread and similar responses, "go with the tune".

 

I think the TUNE adjust Throttle response as part of the tune. Could be wrong, but don't think so!!

 

My car has no lag whatsoever. Love the tune, pulley and CAI.

 

What is a eurocharge tune I keep seeing posts about?? is it something only available in the US??

 

I thought the same thing with just my tune, until I tried out a SB (this is on an NA). The SB makes a huge amount of difference above and beyond the tune. I can turn my SB off and even with the tune, the response, IMHO is horrible. When I put it to the middle 'green' setting, it is absolutely perfect.

He very well may alter the response somehow with the tune, but IMHO, the SB makes a literally night and day difference, and until you have tried a SB, do not call it a waste of money

i could just buy the tuning cable and it will do the job right? Cuz I see there is different things available for the tune

 

Contact Eurocharged but I think they need to make a modification to the ECU for it to accept the first program. Jerry & Team are great guys. Contact them - they will not steer you wrong.

 

You may be right on an NA, but I assure you the throttle response could not be any crisper, on my modded SRT6, and I have an unmoddified one right next to it to compare with. I shall rephrase , IMHO I would not pay for a SB for MY car as it is a waste of money for ME .......not knocking the SB, just don't think the throttle response could be any quicker. I'm quite happy

 

Maxcichon and I have identical 2005 N/A roadsters, had the pleasure of driving his last Saturday and I can attest that the sprint booster makes one heck of a difference.
( his has it, mine does not )

 

Thanks for the responses guys...I've got the Eurocharged Tune (cable) headed my way....Sprint Booster is next...

 

Let me know if it really is quicker with the SB, as mine is difficult enough to drive smoothly as it is, I can only imagine what a handful it would be if the throttle was any more responsive ............

 

I have a convertible crossfire will these(sprintbooster or eurocharged)help its throttle response as well?

 

YES, these will both significantly improve both throttle response (SprintBooster) and actual performance (Eurocharged Tune)....best $500 or so dollars you could spend on a mod for the Crossfire...

 

I was saying because I don't have any mods to it yet n that was going to be first step........throttle response.........but how do u know if its a coupe or a roadster

 

I hate to belabor the point even more but the consensus is for NA XFires that the Eurocharged tune doesn't do much for throttle response? I was under the impression that the tune would eliminate the need for a Sprint Booster until I read this thread. I would eventually like to get both if they are both needed/beneficial but I'm more concerned with throttle response initially as proper downshifting is a PITA with the sluggish throttle in my XFire and it's the one thing I don't enjoy immensely about the car.
