is hypertech chip good upgrade for stock 94 z28 only non stock ption is k&N filter. thank you Allen

 

There's a Hypertech Power Programmer for the 94, and there is a Hypertech Power Tuning Module, but there is no "chip" for a 94. If you are after a bit of extra HP, they are next to useless. A simple mail order tune will cost you less and gain you a lot more HP than any Hypertech product.

 

I second Fred on this. I've compared a hypertech flash file and a stock flash file side by side... and the hypertech had almost NOTHING done to improve power.... only tranmission tune modifications. And with how finicky the 4L60E is I wouldn't mess with that myself...
