I just bought a 1994 Z28 that came with a Hypertech Power Programmer III (Part Number 340752), but it didn't come with the instructions. Does anyone know where I can find the instructions online? Also does anyone know how you set your car back to stock if nothing else? Thanks!

not to be a jerk but the best instructions i could give ya would be to pull the hypertech tune out of pcm sell it and get a tune from 1 of the many ABLE tuners.....so you can actually get power! i am sure many others will agree.....

Thank you ACE! But do you know where I can get the instructions for my actual model? Those are for 1999 and newer cars and duramax trucks.

I have a copy of the instruction manual for a 94 Hypertech Power Programmer Plus. I don't think they changed anything when they renamed it the HPP III. If you want, I can fax you a copy or e-mail you a .pdf file. Give my the info in a PM, if you want it.

I'll add that the HPP is of limited value as a performance tool, but it is convenient for some of the tweeks like gears, rev limiter, speed limiter, shift points, etc.

If all you want to do is return back to stock, you do not need the instructions. Turn the car off, plug in the HP and then turn the key to the ON position. Press the Y button on the HP to turn it on. The HP will you check your VIN and tell you that it has programed your vehical. The first option will be "Return to stock?" press yes and wait. Just follow along with the screen. Its pretty intuitive.
