Thanx for the replies. That's what I figured.
I have a Magnaflow 3.5 single cat back and a Airaid mit kit to install before tuning.

The 2010 tuned 6.2 Chev I traded for this rig would kill it anywhere, so there should be
a lot on the table tuning wise, here's hoping.

I just picked up a new '15 6.2 Silverado with the 8 speed and the tranny makes it drive like a carburetor with an off idle accelerator pump issue and a lean surging issue once going. Much better in Tow/Haul.
