Been tuning for a few years, but mostly gen iii stuff. Got a 06 gto 6.0 and t56 installed in a 57 chevy. I disabled vats 1 and 2. Turned off all related codes. Did write entire and reread to make sure it took. The car will turn over, but won't start. Fuel pump primes, but have no injector pulse or spark. I believe it's in the wiring, but the guy just called me to program it and did everything else himself. Wanting to make sure that I'm not missing anything. Also in my experiences with gen 3 vehicles, if vats was still enabled the car would crank, run for a few seconds then die....is this the same on gen 4 vehicles?
