    boost gauge

    so other night took new NA2T out for first hard interstate run and gauge seemed to read great. it was maxin out about 10lbs reading quickly and consistently. today it wouldnt go past 5lbs and when i hit the gas it would go vacuum then boost. as if it were sucking instead of blowing. i checked for boost leaks (none) and vacuum leaks. my AIV large hoses arent hooked up but its plugged in and the smaller of the 2 canisters front passenger side in bay is wired but no lines. bigger one is hooked up.

    Same thing happened on my na2t I found the turbo manifold gasket blew out, and my tb to charge pipe coupler is junk. Check all your vacuum hoses and zip tie anything vac hoses that see boost

    Zip ties seemed to work good for me, I.had the boost lines that come off the compressor blow off with the clamps on them , zip ties on everything now and everything is holding together

    I replaced my turbo manifold gasket, tb coupler & clamps yesterday and it's boosting like a mofo now. Really look around for exhaust leaks & make sure your coupler is good
