Well I changed to a 69mm pulley I found on Ebay. So I'm running 181/69mm pulley combo now. Fuel pressure has been increased to 70psi. AFRs at WOT look perfect and my fuel trims are staying around zero. Strange that with the increased pressure the ECU is not pulling a ton of fuel in closed loop. Going to put some miles on and watch the fuel trims before bringing it back to Maperformance for another Dyno pull.
