No on street only tuning, that is with 13.0 to 1 comp ratio on race gas N/A years ago at the track and on multiple engine dyno tests with iron and aluminum heads
I have found out since then that when I see 34 degrees total timing someone else may see 32 to 38 degrees BTDC on the same motor the same time
I try and make sure I have my eyes align with the timing tab and the center of the crankshaft when setting ignition timing
I'm going to have to find out, learn, how much timing to pull with NOS this year also
i hope I do it without hurting the new motor
