90 daytona es 2.5 turbo I
rebuilt engine with 2500 miles
giant front mount intercooler
hybrid T3/T4
stock fuel system (adjustable fuel pressure regulator sitting in box still)
stock exhaust system
grainger set to 10psi
no charge air temp sensor
stage 3 computer (fwdperformance)
i'd like to add more fuel to reduce my AFR from 11.4 to say 10.5 at 10 psi. how exactly do I go about doing this?
I would imagine i just install the AFPR and turn it up a little bit above stock pressure.
but then wouldnt the car run rich at idle, part throttle, etc..?
or does the closed loop O2 feedback have enough span to adjust the mixture to be correct even when fuel pressure goes up? (when not at WOT)
I also have +40 injectors sitting in a box, but the stage 3 computer isnt compatible with them so im waiting until I get the stage 5.
