All I have done to the truck is a drop in K&N, Magnaflow 3 1/2" big body muffler, and some tweaking with HP Tuners and she put down 347hp/359tq. The torque curve on it is very nice

The pull was in 3rd gear





Edit: Numbers after Pat G worked his magic 368hp/380tq

 

I hear Clints dyno reads high lol great numbers!

 

I hear there's a white Tahoe going thru two bottles a weekend

Thanks, I was very pleased with the numbers, now it's time to
Get some track times

 

Nice numbers man!

GM Powah!!!!!!!!

 

Hahaha you may have heard right

I bet its going to make some good times. Makes me wish I had a 6.2 6speed

 

Im sorry am I missing something? Thats 402HP at the crank. Aren't they claiming 403HP stock?

 

Yep, you're using a 14% loss for drivetrain and front accessories. I'd bet my front row seat these A6 truck are close to double that, and even worse thru a transfer case.

 

Nice! Thats impressive!

 

Wish I had a dyno up here I could put my truck on

Have similar mods to my truck, would like to have some solid numbers to start working off

 

I'm betting its between 18-22% drive-train loss, and I dyno'd on 22's with 100* shop temps so that didnt help anything. All in all I'm happy and I'm willing to bet if I would spend a little more time on my timing tables I could even squeeze alittle more out of it. But honestly it feels so good right now so Im not even going to bother till I put some good power adders on it. Right now Im torn between a good quality Nitrous system with stand alone fuel and nano assist pushing around a 150hp pill, or a whipple.
