Hey guys just finished my lex/afm mod on my supra with some 550 cc injectors everything is running ok i'm real rich at WOT air fuel ratio's dipping in the 9's but mostly straight 10's question is, is it because i'm at sea level that my fuel cut is only around 15.5 psi and how can i raise this? i don't have a custom AFM housing with modified adjustment screw can this be adjusted with the stock air screw? Also should i try lowering the base fuel pressure currently i have it set at 30psi with vacuum on.
