Let's try something easy

[GMTECH704]

Okay, I trying to eat the whole Apple instead of one bite at a time. Is there some easy tunable things I can do to this 4.3 l vortec two make a little bit of a difference? I have already played with the transmission and torque management, no I did not zero out the torque management. I think I started off on the wrong foot with this tuning process. If you guys have any suggestions on some easy steps maybe spark advance or anything! I'm just out of loss right now. Once this season is over I am swapping to the 5.3 l I just have to finish building it. Again thank you for your time.
Side note the truck does have a cold air intake and I do run on 100 shot nitrous Express wet kit on a progressive system at one point five seconds it runs 10.5 on motor and a best of 9.3 on the wet kit.

I mean yes. You'd want to optimize your air fuel ratio on gas to make sure it's running the best it can at full throttle using a wideband. And try to optimize the timing. Hard to say what degree of timing at full throttle will be best. A dyno would be key for that. Most stock engine LS's will take low to mid 20's for timing. But when you add NOS, probably a good idea to have a separate tune that has less timing in it to save the engine from knock.
