Hi, I have to learn to tune.
1992 Blazer K1500 4x4, fresh 5 speed conversion, fresh 6.2L 1pc seal, RamJet cam, Vortec heads, 1416299 ECM, 1.930" TBI, 65# INJ, Tri-y single, high flow cat, second bung with Innovate WB MTX-L .
Old school SBC carb guy, I've been using pre-burned chips, need to pick/try directions, I'm seeing tons of good information here, getting hopeful I will be able to keep GM ECM.
