Looking for P59/12587603 LQ9/4L80E 4x4 Stock bin

I recently purchased a 2004 Silverado 2500HD Single Cab Long Bed with a swapped LQ9 into it. Nothing done to it and I think the current tune is lacking significantly. Thank you!

The LQ9 never came with a 4L80E behind it. Will need to segment swap to create a tune for that pairing.

Yeah, I just used the following for it to run way better than it was running. The no vats one is the one i modified to account for DTCs and no cats. Would someone help me better tune it? I just want a better driving truck.
