well i got my 550cc injectors in, im getting great gas mileage with my low trims.. and great timing advances at WOT without black smoke coming out.... problem is its backfiring alot... just little backfires nothing big, just normal sounds after accelerating. am i still running really rich? or is that just part of it? or does it have to do with my spark plugs? cause they took a beating tuning these injectors
