In theory though, if accelerating with WOT, then there would be no gain to be made right? That said, those that have purchased it (like yourself) have benefited mainly from the increased throttle response from lower revs which is basically speeding up the rate in which the throttle position changes. I personally think it is a trick of the mind thing, but I can't comment since I personally haven't tried it. Still curious to see how it affects your 1/4 mile times though since you are one of the fewer people out there who would be able to test that and post results (no one else seems to say anything). I would imagine that providing you never broke traction when mashing the accelerator from a standing start, then by being able to increase the throttle response, you should be able to gain a measurable figure.. even if it is 0.1 seconds.
