In the words of Joe Dirt, Im new, I don't know what to do.. (e67 08 5.3)

Okay so, I have a 2008 Envoy Denali with a 5.3.
I'm not new to hptuners, but I am new to tuning myself. In the past I always had tuners to dial things in.
There are no "canned" tune options for this car, so it has to be done through HP.
I started by turning off the DOD, and associated cels.
I attempted to adjust the pedal sensitivity and turn off any traction control, then adjusted some torque limit stuff, only to have the car throw a light for the pcm on 10 min ride afterwords.
I'm back on the stock tune, with DOD deactivated now.

Where should I be looking to adjust the throttle sensitivity?
I included the current file as reference.

Also, this is a selectable 4wd model, run primarily in 2wd. Trans is a 4l60e, and the truck came factory with a 3.73 Eaton locker lsd rear diff.
Exhaust is currently factory manifolds, gutted cats into a turndown.
It should be way peppier off the line then it is.

Add timing where you can. That is how I improve throttle response

I do not recommend changing pedal stuff. It can cause PCM problems like REP codes

Yeah, the PCM wasn't a fan of the pedal percent changes.
I have revised the 1st tune to add in turning off the trans abuse mode, and any fuel torque management. That has made a huge difference in drivability and off idle response.
I'm wondering now if I should turn off the spark torque management also..
