2011 GMC Sierra 6.2L Pat G Dyno Tuned
#12
So what pat was telling me was he likes to be a bit conservative on the tune cause of the amount ethanol in the fuel, so he normally shots for about 12:4:1. I know the guy that tuned my Iroc shot for about 12:75:1-13:1:1 on 93 and he was running 27 degs of timing with my motor being 11:1 compression.
My Truck however on that particular run was pulling some timing around 4500-5k, initially he was running 23degs of timing, I believe he backed it off to 21degs.

Nice numbers. I had Pat spec me a cam and am going to get him to tune it after I get it installed. Hoping for abot 420 or so to the wheels. With so many of us in the area we should arrange some sort of meet sometime.

I totally agree, maybe we can hook up at a twin peaks or Buffalo wild wings on sunday for some football as well !
