you don't have to test that high. I'm running over 30 psi so that's why I test that high. I would just test to like 15 or 20 if I was you. The stock boost gauge is useless.Where would u suggest i attach the tester, i hooked it up to the the throttle body and lower intercooler piping. Should i attach it to the turbo inlet? And wouldnt 40 psi damage something?
Ok but how do some 2g dsm drive totally fine with no modifications when they swap a 14b
Hmmmm those seals failed on me immedieatly with those style injectors... may want to check. Those should require an fic seal kitI always use new seals I need to do the BLT, I crashed out the other night, just need to stop being lazy!You must be logged in to view this image or video.

FIC seals always leak anyways. Not terrible, but they leak.Hmmmm those seals failed on me immedieatly with those style injectors... may want to check. Those should require an fic seal kit
Not as bad as using those dsm ones on that stule injector. Mine literally explodedFIC seals always leak anyways. Not terrible, but they leak.
so did my FIC ones but they were very old.Not as bad as using those dsm ones on that stule injector. Mine literally exploded
I destrpyed 2 sets of oem before i figured it out... oh well live n learnso did my FIC ones but they were very old.
I think a lot of people are confused on how bov's and wastegates work. The bypass valve is normally closed due the the spring pressure this holds the bov shut but not well enough the reason for the vacuum/boost line it 2 fold. Under boost above spring pressure boost fills on top of the diaphragm helping the spring. When the throttle plate closes between shifts boost turns to vacuum the line then vacuums above the diaphragm and over comes spring pressure opening the valve. This is the only real reason for the spring waste gates work in the same way. Just reversed vacuum helps the close and boost opens mbc bleed off set psi to reach higher boost psi than the spring can handle. But if exhaust pressure surpasses spring pressure the flap will creep open no black magic just good old mechanic theory most important thing when coming to turbo cars vacuum lines run both ways vacuum under vacuum and boost under boost. N/a cars only run vacuum. I think this is a concept some people over look when moving from 1 car line to another and y boost leaks cause so much problems so some leaks will hold vacuum because it's suckling the seals in. And there may be something there that helps the sealing like a lip or boss around the injectors. But under boost these seals get pushed out with nothing to hold them in place remember the KISS method. Don't over think things and. Keep It Simple Stupid.
