42# injectors, 80mmMAF - advice needed

[MustStangEst]

Hello,
Pleasee give me some advice. I have 70mm TB and fuel pressure adjuster installed to my 95 GT. It worked very nice with raised fuel pressure.

Now I installed 42# injectors with 80mm MAF calibrated for 42# injectors and I got some problems with running idle and also decrease of power.

Could someone give me good advice for fuel pressure number to get right A/F ratio or is there any other possibilities to get my engine run well?

Umm...if your trying to run 42# injectors on the stock EEC then good luck. My car barely ran with 42's. With my autologic chip it idled at 875 rpm with zero problems.
