what are the mods your running? i recently installed the dashdaq system in my car and readings are 14.7 afr at idle and 12.5 afr at 140mph steady thruought the acceleration range. my mods are conservative with only the c3 pulley intakes and dyno tune with no changes to the fuel system. i run 55 psi fuel pressure with max boost at 18 psi. iat's run @ 95* F AT 80*f outside temps.
i can datalog a run to max if anyone wants it
