When I first did my 1500HD with my G-tech Pro Competition I got these readings :

RWHP 203.2 @ 4765RPM
RWTQ 261.1 @ 3915 RPM

So these figures are not dyno or sae corrected and include wind and road slope if any but are probably representative. I also find they are reasonably repeatable.They represent drivetrain losses of > 30% and are obviously a little on the low side. By the way my truck with me in it weighs 6050 LBs according to the local highway scale and is Auto 4x4.

I posted my G-tech runs with my 1500HD a while back too. If interested, let me know

I don't know.....I put down 321 ft/lbs completely stock with the same tranny/rear-end combo that grippy has, and that was with 34,000 miles on it. I think that 323 is believable

my HP dyno number on that same run was WAY off in my mind though.....so I could be wrong here

I'll have some further baseline dyno data soon, double checking my numbers to see if they are repeatable
