first off the car and the current setup...
91 shadow A413 2.5 w/T2 Garrett
Diode, Turbo XS MBC
2.5inch FWD catback pipes, dynomax muffler
Magnecor wires
SRT4 FMIC, custom IC piping
255 lph pump, AFPR, fuel and boost guages

Right now the MBC is set at 13psi w/the stock injectors...i have a set of 20's on the way...my question is, with the stock computer, can i up the boost to 15-16psi or so w/the higher flowing injectors? and also, what should the fuel pressure be w/the vacuum line off the AFPR at idle? i know its gonna take some time to tune it...thanks for the help :thumb:

With the +20's to be stock, you want 39 PSI of fuel approximately. This will MATCH the flow of the stock injectors. Then its time to start to tune the RRR to get the fuel you need over 15 PSI.

Good luck with it, a good reference for this is Gary Ds site on larger injectors
