People having problems with the car not moving at all!
Lowest price sold so far is $200.
Someone reported that gas mileage plumeted pretty seriously. He reset the ECU and I believe things are fine now, but haven't confirmed. I wrote him a PM just a moment ago.
Some say that it wears out the transmission and belts hella much.
Another guy had an experience with it skipping gears!
Supposedly the Sprint Booster increases the throttle response, but also when you let go of the gas, it comes to a halt much more quickly.

I absolutely love it!

who ever posted that thanks! what a great read!
allow me to quote the final conclusion, "The Sprint Booster is a simple amplifier that multiplies the accelerator pedal sensor signal, making the accelerator pedal feel more sensitive. It does NOT eliminate any signifcant delay in throttle response, nor does it greatly improve acceleration figures. It does NOT change the adaptive throttle control programming of electronic trottle control vehicles. It DOES change pedal "feel". This change in feel is interpreted by some as improved throttle repsonse, acceleration, and a change in adaptive throttle control programming. Considering what it actually does, it's expensive"
I'm NOT buying one. :-P

My friend let me use his sprint booster, and yes it does make a difference. The pedal does not "feel more sensitive". It does not change the pedal "feel". The pedal moves as it normally would, but the response is instant, no delay.
for what it's worth- the sprint booster does do what it says it does. it get's rid of the lag. do your tests all you want- it does what it says it does- nothing more, nothing less. it improves throttle response- no matter how it does it.
Having said that I've just about read through all the threads regarding the topic as well as the "white paper" PDF document and have come to this conclusion (as someone who has yet to try out the product). I believe wholeheartedly that it does what people claim. It "feels" faster. Better response. No lag. But at the same time (me being the idiot that actually read through most of the 200+page manual for our cars and found out), if the pedal is pressed lightly, the car starts at 2nd gear. If pressed quickly and hard, it starts at 1st gear. There's naturally a lag when car start in second gear.
That fact that the lag disappears from the installation of the Sprint Booster is no surprise. It's open throttle at initial contact of the pedal and therefore starts at 1st gear.
WILL I BE BUYING THIS PRODUCT?
I haven't decided, but leaning towards no. There are just too many other things I want to buy at the moment (springs etc) and the loss in gas mileage is what's turning me off since that's one of the major reasons I bought the car. I know that's not true for all of you, so do what you will.
Before?
After?
Mind sharing?
Can you shrink your sig pic please? i love the car and it looks great, but it's hard to navigate through threads youv'e been in b/c it's so darn huuuge.
also- as a side note- i would appear that his sig is roughly the same size as yours....judging by strolling distance

ANY performance upgrade will probably affect your gas mileage for the worse. When you modify your ride...some things work, and some things don't. Take a look at more of these threads, like the classifieds, and tell me what you see...folks selling something to buy a different something. I have gone through 4 sets of wheels in ONE year because I couldn't decide. It takes more than reading about something, asking somebody else, or over rationalizing in your head, to really KNOW what works for your car. I can respect the fact that you are doing your homework but come on...you're on 3or 4 different threads and have started a new thread over a stupid sprint booster! Just BUY it and sell it if it doesn't work for ya. It is the cheapest upgrade you will EVER do. Ya gotta start somewhere.

very well put. The mileage question was simply out of curiosity since it indeed changes driving and accelerating patterns which can affects gas mileage, to what degree, it seems minimal.
All the thing does is electronically cut your pedal travel by about 2/3's. So 1/3 down is now "WOT". I found it made my car too jumpy to enjoy, but got used to it more than I expected - when I pulled it out it took a couple of days to get used to the feeling of it gone.
The majority of my driving is stop and go city traffic, with speed cameras thrown in for good measure. I found a consistent 10% reduction in mileage.
When on the highway, it was only about 6%, but still very measurable. I consider myself to be a pretty conservative driver, so maybe that's why I noticed it more, and liked it less.
I still think it's about $6 worth of parts, in a nice convenient, plug and play cable and connector form.
