    it depenands on the turbo, whether it is intercooled or not, and also what have u done as a fuel upgrade.
    With warlbro 255, and vortex fmu i blown my pistons at 4psi on 16g turbo.

    you should get a boost sensitive rising rate FPR. that is what i have. at idle it is around 45 psi and when full boost comes on it goes up to 65psi. in the begining i had problems with the fuel pressure droping off, so i put in a walbro 255 and didnt have that problem any more. but now with the bigger injectors i got, i am not sure cause i am still breaking in my engine. 700 miles down. i boosted a little this past weekend cause some kids where F#@%in with me
