Do not mess with timing adjustments without some form of datalogging.Take it to a dyno; improper toying will ruin your motor.

actually my main concern is if it works well and if it is reliable and consistent. my problem is initial advance is set really low and final advance set really high, so i get knocking sometimes. i really need some way to retard timing at top end?just wanna now if the thing works,cause right now i dont have enough money for stand alone

thx a lot

by the way the cars running 13lbs boost and have fmic and gt2530, cant put more boost on without retarding timing
