i'm runnin a PPE standard with the PPE boost valve and i usually have it at a 220hp tune and i haven't seen over 28psi. except once and that was goin uphill at 70 and i hit 29 for a split second. normally i'll hit 25psi tops. so you should be perfectly fine. But yes listen to FastCR, GET GAUGES!

boost valve takes maybe like 30 seconds to install.

you cut the rubber hose in the front of the turbo that goes to the waste gate in half and pop that valve in and hose clamp it on
