where can i get a new pcm for my 96 3.1 ls monte?

 

junk yard or dealer...or check ebay

 

where can i get a better pcm for the 3.1? I want to get rid of the rev limiter and the gov. I also want it to change my shift points to a higher rpm

 

I've NEVER seen anyone offer a PCM for the 3.1 as it is not typically used as a platform for performance - it was designed for gas milage. You may be able to get a programmer for it: http://www.pfyc.com/pc/GN7021/MCUNDE...PowrTuner.html.

While it will greatly help someone that only wants to keep their engine NA, there are alot better bang for the buck deals out there and it depends how far you want to go with your setup. Since it's a 96 and probably has a ton of miles, you might just want to consider swapping to a 3800 for much more performance and a whole world of options.

 

yeah i plan to convert it to a 3.8 ss punched out to a 4.2 turbo. i know im in for a lot of work but all i got is time.

 

Don't know anyone that punched it to a 4.2 yet. You might be one of the first people on the various message boards much less having it turboed.

 

i have a couple of friends who have punched out 3800 grand prix motor and they ar supercharged. I just wanted to do something different than i supercharger i sort of wanted a turbo or something like that.

 

The turbo will allow you to get huge gains of power over the roots supercharger. There is still some investigation on the Whipple supercharger, but only about 4 to 6 people actually have them and their cars really aren't modded yet.

Hoping someone can go gungho on one to see what it can do.
