There are many chip out on the market. But I wont to know which one will make my 01 gt (auto ) perform the best?

Is it Hypertech, venom,etc.

Off the shelf chips are a crapshoot at best.They are a generic tune that is a one size fits all.They can firm up and raise your shift points,eliminate top speed limiters if you have one,and raise the rev limit.Most only make adjustments to spark and fuel at wide open throttle.

Get a tuner instead. They run about $400 and can do a WHOLE lot more.
