I have aem wideband in mine. Makes things much easier. Also an adjustable return style fuel pressure regulator can help fine tune it into the appropriate AFR you want. Best to get it where you want running tits before the spray. I have nx plate. 175 pills 6.2 degrees of retard set info the digital 6al2 box. Runs right about 12.2-12.5 afr on the 175 shot. I have a aeromotive fpr on each of the fuel systems. I don’t care what base timing is. I set my timing at 36 deg at around 2400 rpm. Timing mark on the plug is dead center of the strap.
