2000 S10 with a 2004 5.3 motor swap* and 4L60E trans.
*when I did the swap I took every single wire, along with the gauge cluster and steering column out of the S10 and replaced it with every wire, steering column, and gauge cluster out of a 2004 Silvarado
That being said, I have a 2004 1500 Silvarado.
Motor mods-LS1 cam with beehive springs, and an LS6 intake/injectors.

I want to start with a stock tune, and tune it from there. So I downloaded one off of Tune Depot and went through and changed everything to be the way I think I want it.
I flashed it into the truck and it was super lean, and the rev sounded like it was under a little bit of load while in park.
Here is the tune I put on:
Branden-Starting point.tun
Script file of what I changed:
Branden-Starting point.txt
Can anyone see anything standing out that would be wrong with it?

Thanks,
Branden
