Installed mine today, seems to give better throttle response and beyond that it was hard to test because it was raining pretty hard here. Looks great though. Of note, I did not pull the battery connection-- I would prefer that the car learn from its current position rather than base, because this is a small mod compared to the headers already on the car.
To the guy who is having the bucking and hard starting -- make sure all your connections are intact. I had that problem with my other car on a maf, turned out the MAF connector wires were not firmly pressed in.
