I have 20* at 2000 mechanical. 8* in the vacuum can. In cruise I usually turm between 2/2300 rpm. I set the AF at around 15+ Hard to get with the 2GC. Using 51 jets now. PV drops it to 12.8/13.1

I have a megasquirt universal engine management computer that was given to me. I've picked up a GM throttle body from a 90/96 truck/ I have a 4bl intake I can mount the TB and just run the computer for AF and Ignition timing. Got too many projects going for my age, and i feel like a roll of toilet paper. I;d jut like to know the limits of this tuning sh*t. Get fom facts, everybody has a different slant on it
