wow, what a read....I wouldn't buy anything I didn't think would work....They will plug in wrong btw...Last one I did was my own as my throttle peddle's rubber cover came off, causing the throttle peddle to stick...10 minutes tops...once you learn how to get the washer out...I use a magnet that looks like a pin...most mechanics keep one around. Fish out the washer, the rest is easy. They have a correct way to connect, but will connect right/ or wrong...you have to do a throttle reset...and I would do this a couple of times, as throttle resets aren't perfect either...then drive the hell out of the car so it will learn all over again...throttle should be instant...no lag...as mentioned above, it will improve your reaction time in the quarter mile racing...nothing else...it just gets rid of the lag...expensive, yes, but I hate lag...
