Is this the issue that the Sprint Booster is designed to fix? Is there anyone in the Atlanta area that wouldn't mind meeting and letting me check out their throttle before I spend a couple hundred $$$ on the Sprint Booster?
Thanks everyone.
It's very easy to rev match the throttle to gear shifts. what you do is, right before down shifting is blip the throttle all the way to the floor, it works perfectly everytime. just takes practice. Those Sprint booster things are expensive, for that price your halfway to sending in the ecu to get re mapped for more power and better throttle response by the guys a SI.
I think the SB is more of a cheap band-aid fix. And it doesn't really fix the lag unless you reset the throttle every other trip, the manual version is way too sensitive to use on the street. Just spend the money on the ecu upgrade from SI.
