With my car I had the base timing off. So when I set the timing at 20 BTDC it was really 50 degrees BTDC. We didn’t notice any performance change at the time because boosted cars are a handful as is. But upon disassembly i found the headgasket had leaked at some point. Subcom is right, there should be a way to command the ecu to lock the timing at a value you choose. I do mine at 25 degrees so that the motor stays running while I am doing it alone. The value you see with your timing light should be 25 degrees. Any variation of that will affect your timing when the computer is managing it. As far as coil dwell time goes, it will misfire not be lazy. Also pick up air gap will not make it lazy, it will be fine or not start pretty black and white. TT5.9mag also has a great point. In the past on another turbo build we had too big of a cam (which would act like a retarded cam) in the motor, and it wouldnt even build boost on the dyno. This goes back to my original point. Do we know the engine is running properly to begin with, N/A.
