My z with 750cc injectors 450 walbro tomei fuel pressure regulator

Iwas set the regulator to 43 psi the car was cut and the turbo bost about 10 psi

 

I rise the fuel pressure to 50 the car hits 15 psi of turbo boost

 

Fuel control unit deleted

 

Is it OK ti rise the fuel pressure

 

Its effects the idel i think do i have to tune it again

 

My turbos is gt28

 

I need advice guys

The OE fuel pressure regulator should maintain fuel pressure at ~36 psi at idle with vacuum reference attached, 46 psi at static manifold pressure, then increases fuel pressure 1:1 per psi of boost.

this is a good read..

46 psi fuel pe for stock boost about 12 psi

For 15 psi i should rise the fuel pressure to 49 to 50. Is that right

Why do you think that raising the fuel pressure increases the boost?

Ok my car had big injectors 750 cc with 450 walbro and I'm using tomie adjustable fuel pressure regulator so its could be different from the stock direction

I want to open 15 psi howm much i should put the fuel pressure cuse if it's at 43 stock the car cuts out at 5500 rpm

Look like its starving of fuel

I think my boost controler is damaged cus its set about 15 psi but last night a drive it with higher fuel pressure about 50psi

The car hits 20 psi that's weird ?
