well finially finished. 6.0 LQ9 and rebuilt 4L65 and dyno tunned. 288 to the rear wheels on 89 octain.

What gear ratios does this truck have? Saw your photos with the trailer attached and was wondering what your GCWR might be.

3:73 gears. I think I am over my GCWR. But it’s not for long. Going to buy a 3500 diesel when I find one with out a million miles.

I had mine black bear a couple weeks ago at black bear, and it’s like you said @#1taho , it’s so worth tuning because it’s a whole different beast now! I’ve been having a ton of fun last laying all the goodies from the tune the last couple weeks!

2WD Tahoes came with 3.73s and a Max Trailer Weight of 7,700 pounds with a GCWR of 13,000 lbs. The 4WDs had either 3.42s or 4.10s and 7,500 or 7,800 and 13K or 14K respectively. Your LQ9 can certainly handle it but you might get a ticket for running over.

It's a nice looking truck.

Yes I know I could be in some trouble if I get pulled over. But it’s the chance I have to take for now. There is a bigger truck in my near future. I think the last owners ordered it with the 3:73 gears. I am the second owner and know the original owners. My biggest concern twining is the tranny. I did all the steps to help prolong the enedibitable but it has tones of power and handles well.

I was going off the 2005 Owner's Manual. Anything's possible it seems! Those are better for working with the 4-speed anyways.

I had 3.73 in my 2000 Z71. My 2006 has 3.42. It's nice on the freeway, but I think I miss the 3.73s.
