The Ecu is awesome like jordy said it makes it a whole new car. It gives it alot more top end and launching power. The MAF for the money isn't worth $275 it provides low end power but its nothing amazing for that kinda of money. Royal purple added alot more power for cheaper I think.

Plenty of people have done it and most everyone is very pleased with the results.

I just said that because this place is pretty inactive with its members base. If you want the opinions of many gt drivers there are bunch of threads talking about it already you would not need to ask. I know a couple of guys that have gt's with a vector tune pretty good also.
