Hello, new to this forum and slightly new to ECM tuning, at least to this extent. About to fire up a 63 C10 with an 09 Denali E38 ECM with PSI standalone harness. Engine is a 2018 GEN IV 6.0l with cam swap and holley intake, MAFless system running Speed density. Wanted someone with more experience to look at my start file and see if I have covered all the bases to get this thing fired up. IE, Vats disable, MAF, VCT disable etc. Thanks to anyone who takes a look at this.
