is it bad in idle to run your FPR at 32-35PSI? i no ur sopossed to run 43 or something but my a/f is so lean when i run that and it stalls itself out

 

? Its lean at 43psi and you want to run 3X?, that doesn't really make sense to me. I could see if you would want to run more fuel pressure than 43. But again that's not really the right way to do it.

I think you should have someone look at your fuel maps.
What is your afr at idle?

 

The higher the fuel pressure you have the more fuel you can push through the injector when its open. Thats why fuel injectors are rated for higher flows at higher fuel pressures.

Or at least that is my very basic knowledge on that topic.
