Anyone tried the Sprintbooster

[jaykay]

I looked at pedal position versus % throttle body opening, pedal potentiometer etc. via Durametric when I modified my pedal box for an adjustable pedal. Essentially I was adjusting the full throttle stop position on the new pedal to exactly match the 100 % TB opening and potentiometer movement.

If the Durametric software is accurate then the response to pedal movement is pretty darn good. It snaps to 100% right with your foot, with little delay. One would have to look at other areas such as: intake and exhaust acoustics; fuel trims; cams....and on to get real engine response.

Ergonomically, 100% throttle at 75% throttle position might be uncomfortable

My girlfriend's 4 cyl RAV4 is pleasant to drive partly because it's peppy at low speeds and feels like it has a lot more to give (but it doesn't). Once at half throttle there isn't a much left. But this must be how they do it.

The product can be tried for free..........30-DAY MONEY BACK GUARANTEE* This is a product that you need to 'feel' to believe - we are so confident that you will LOVE this product, we are offering a 30-day money back guarantee - no questions asked.

Can't ask for much more than that....!

My 2.7 Boxster (5 spd) really needs to be pushed to feel it's power, which is kinda limited. This might be what it needs for drivability reasons. But $289 is a lot for the product. I'll keep an eye on this thread until Spring when it comes out of Winter storage.
