I am just on a 16g like you lol.

I have gm maf, and I run 850cc injectors with 47.6 psi base fuel pressure all calculated into the chip. 11.3 afr, I tuned my timing maps myself and I was on like 24 ish psi when I raced you.

I need to buy a fresh pack of chips but perhaps we can set something up were I can help you edit your tune.
