My friend has offered to sell me his barely used Superchip Max Microtuner for
only $200. Since they sell for about $470 this seems like a good deal to me
but what do you guys think? Is it a good deal and how much will it help my almost stock 02 GT?

 

dont bother superchips makes some very genaric tunes. I had there tuner on my truck it was awful did nothing and my 1/4 didnt even drop a bit from it. I was pissed to say the least.

 

Get the xcal2, you'll notice a difference.

 

get something other then superchips. get a Diablo or a SCT tuner.
