GM Stage 3 ratings:
248hp (93 octane)
260hp (100 octane)
310hp (nitrous)
(Ratings are from GM)
My car made 256whp last fall with the GM Stage 3 tune & pulley + AEM Intake, 42's, GMPP Manifold, & GMPP Touring Muffler welded onto the stock catback.
P.S. I still had the M62 installed at the time.
I highly recommend the GM Stage 3 tune. It's much more aggressive (11.3 a/f ratio, 23 degrees timing), and is an all around better tune than GM Stage 2. Also, you can now have A/C enabled & get it custom tuned by Trifecta performace. This is something that was never offered before, because the tune used to be locked.
