How are you going to tune flex fuel?

 

Based on your other questions and inability To search I'm guessing you did nothing to the fuel system other than drop that massive pump in the tank...... That ain't going to work, it'll overun the stock fuel pressure regulator.

Take about 5 steps back and do more research before your project ends in a part out.

 

I have a person that will tune it for me

 

I did upgrade pump and injectors and the rubber fuel lines but i didnt read anything about the fuel regulator

 

On the '90-'97 cars, the FPR is referenced to manifold pressure, so the fuel pressure will always be roughly 42 PSI (median) above manifold pressure. Or put another way, the pressure differential across the injectors will always be ~42 PSI, and therefore the flowrate of the injectors will be a constant. I wouldnt think that the pump will over run the regulator if i have big injectors ( correct me if i m wrong)

 

You still gotta idle bud, wot will be fine but I betcha you won't stay at 42 psi under low load.

 

I leave that to my tuner for the idle. any recommendations on an after market regulator ?
