Gm Stage 3 ?
Hey guys i just bought a Gm stage 3 PCM from one of the members on the forum. Im just curious if i can run Lucas 42# injectors and a 3.0" pulley with that tune. or what would be the best pulley to run. I know that the stage 3 comes with a 2.99" pulley thats why i figured i should just run a 3".

Im not going to spray. Im not a big fan of nitrous cause ive seen to many things go wrong. I would really like to hear some more info about running a 2.9" pulley on a stage 3 pcm. thanks guys

Since a few months ago actually.
Simply put, the S3 calibration can now be modified just like the stock one.
Airflow, fuel, spark, everything.
This means you can upgrade to 80# injectors, harrop, etc and still utilize the HOM switch and user adjustable rev limit.
The only things that are still elusive are the nitrous mode (due to lack of test data) and the A/C.
Since the testing was done with an 06-07 cobalt version of the calibration, any others would have to be mailed in to be read. (e.g. - 04 redline, 05 cobalt/redline)
For those who don't already own GM S3, you can purchase a P12 PCM from ebay or any junkyard, and have it flashed with the S3 cal + custom tune for cheaper than you would from GM.
If you own a Trifecta EZ Flash cable, you can just flash your stock PCM back and forth instead of physically swapping it out.

with my 2.85, i run a full exhaust header back, i also have all the proper monitoring gauges.
dual areoforce and a wideband.
the stage 3 tune is better than the stage 1/2 tune.
more timing and not pig rich.
i dont hammer it in the winter cuz its not designed for to be ran in minus sub zero temps .
in the summer it runs excellent, and works better with stock plugs other than anything thing else.
i also spray water. i use a custom trunk mount kit plus the dual pass option b and a heat exchanger(front mount)
last summer my tank sprung a leak, so i didnt spray and i did notice the comupter pulls timing here and there in the upper rpms (anywhere between 6500-7000) but its nothing crazy.
so if you wanna get a 2.85, it works great but youll need more cooling.
