"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."

No i can do the math and get the rear wheel numbers. What Im saying is the truck is already rated at 403hp and 417ft/lbs of torque at the flywheel from GM. Subtract the 16-20% of the drive train and thats what were at stock "at the wheels". I want to think that by adding a CAI and exhaust it would have at least gone up an extra 15-17 more Hp over the stock numbers and more actually with the tune.

 

the factory exhaust is actually pretty efficient so theres not much to be gained there but sound, and I am sure with a CAI there is a small gain but mine doesnt have one, just a drop in K&N which with the factory intake tube might not net much at the wheels. Plus when I made this pull I hadnt spent much time on the timing tables so there is room to grow.....

 

Are you doing headers? If so what are you considering?

well made a trip down to see PAT G today and he schooled me on some tables I wasn't brave enough to touch on my own, he tweaked my cam phaser and VVT spark tables and we found some more power out of the truck, ended up 368hp & 380tq. So to say the least I am very pleased and big thanks to patrick for polishing up the tune for me.

 

368/380 on a freakin stock truck with exhaust....not fair lol

 

Yeah, me and Pat were pretty suprised when we first saw it lol

 

Wow what a difference. Where's pat located?
