speed limiter removed, shift points moved, 3-1 4-2 shift skips, possible increase of mgp(nothing major), but youll have to run premium gas.
No huge benifits but i would say it is worth it, especially if you plan to do other mods.
Here is a good link PCM for Grand Prix GT v1.0: 3800 Performance
it is so worth it! but you have got to have to supporting mods installed first. The PCM is the only way to let your car know what it needs to do once you have changed out all the stock parts. Without it your car is like WTF is all this stuff you did to me, am i on acid or is my pulley smaller?
blue what would you recommend to get the low end tq back after the HV3 and dp combo?
Ok blue thanks a lot for the write-up. Just want to let you know, currently my engine is a year 2000 (my 97 engine blew), I have a rebuilt transmission, so that means its still weak correct? And I have a u bend delete and a custom Short ram intake
and new plugs/wires. That's about it. So still should my first step be getting a new tranny? I just paid 1650 not to long ago for a the rebuild =/
If you have that much into a tranny i dont think any tuning PCM mods would be worth it. The PCM raises shift points and makes them harder and faster which i dont think would be good on a rebuilt tranny. It still needs a good amount of time to break in. I went through 2 transmissions not waiting and holy cow $1600 for a rebuild? Did you bring it to Tires Plus? You could be boosted and then some for that price!

Actually a local shop but the paperwork says it also exchanged torque converter? Not sure what that is but I also have lifetime warranty with them as well
Hell, NICK AND I put my tranny in, and two days later was making 10+ passes at the track. LOL
