z28justin did you buy the tuner cats program? im looking into but i dont know how complicated it would be to tune my own car

93Z M6 Black:
P.O.S. Nutech 383 with spun bearings and destroyed Callies crank!

Wonder why that place is outta business

Yup, I got the engine (I thought) right before everyone started having problems with him.

i have a hypertech tuner and think it works fine

Yea it was the place to go to in the early Lt1 days and then things just fell apart.

Everyone likes to dog the hpp lol, but i remember the day after I got my 373's in my old 97 A4....I put there programming on hit the gas and my friend(had a full bolt on 93) an I looked at each other w/ our mouths wide open. It was a huge sotp gain. Torque or whatever the car felt faster for sure, seems like I used a little more gas though after install. I never had a problem w/ mine either :)

Hypertech and other handhelds like that work great for gear/tire size changes and things like that. But if you want to actually tune the engine, get a real solution.....

Yea I originally got it for the gears, back then there wasnt as many tuners around as there is today. For a bolt on car I thought the tuning/160 therm setting was fine, shift points were kinda cool also.
