If you have it, please let me in on the pros and the cons. Also, is the superchips programmer suitable for an engine with a different camshaft, like mine (LT4 Hot cam)? If not, what would you recommend? Any good tuners out there who won't charge me $400 for a tune that won't do any good? By the way, mine is a 1997 z28 M6 with the Hot Cam, Moroso CAI, SLP headers,
!CATS. Thanks.

 

I don't know about Superchips, but I charge $125 + shipping for OBDII programming and I stand behind my work. If you don't like it or think it didn't do you much good, I will return your PCM back to stock and give you a full refund on the programming.
