2010 6.2L/6L80 Sierra bolt on results (stock CAM)
I swooped by the dyno today made 367rwHp/390rwTq. Gained 44Hp @ 5,200rpm and about 40rwTq across the board after adding headers, UD pulley, and dialing in AFR/Spark with a personal tune... I was turning clod hopper 295/45/22's during both runs...
Top run: AFE Intake, 1 3/4'' AR Headers, 3.5'' Gibson Exhaust, UD Pulley, personal tune
Bottom run: (April 2010) Varram Intake, 3.5'' Gibson Exhaust, stock tune

those are some awesome numbers from very little mods. Im about to bite the bullet on ordering a 2011 ext cab 2wd, 6.2/6l80e combo with 3.73 gears. Is yours a 2wd, and how are the 3.42's with the 6 speed. Im getting tired of modding the hell out of my 5.3 ls1, and losing mpg and gain very little.

These tires are usless when the temps are cool/good for making power...

VERY nice #'s, Mark.
Patrick G will be dyno tuning mine with wide band in two weeks, hoping for results as good as yours. Though - I don't have BH (before headers) numbers to compare to.
What kind of dyno did you do your pulls on?
EDIT: never mind - I see it was on a DynoJet dyno. I believe that Pat G. uses a Mustang dyno, so a direct comparison to your #'s won't be possible.

Yea, I see DynoJet's read higher than a Mustang dyno...Shoot i'm just a DIY tuner, Pat G may be able to unlock some real ponies..please share when you are done...

Hey what's a good street tire that still does ok at the track? My 22's gotta go need more grip and less weight...dis bitch will see 12.999 on stock CAM, it's going to take some new shoes or maybe some slicks
U got 4:10's on a 6L80, Damn Hoss? Does 1st gear feel useless at times for daily driver?
