I know I'm asking for answers without the proper logs but I'm wanting to know if I'm on the right track with this tune
I have a 5.3l lm4 , sloppy stage 2 cam, 92mm throttle body, tbss intake, ported 862 heads, shorty amazon headers , 2.5" exhaust, 30lb injectors, and 4l60e 2600 converter, 373s
No O2s at the moment
the truck is slow, zero power and certainly unpleasant to drive, the old stock tbi 350 was way more powerful
I pulled 10% timing and 10% fuel from this tune and it got worse, just looking to make it safe to drive under it's own power and I'm overwhelmed at this point and not sure which direction to go
Any tips or theories or direction would be appreciated so I can better understand what is going on here.
Will be putting a wideband on it soon but I have a 2 hour drive in the morning before that can happen
