recently was hearing a vacum leak at idle. engine still runs good. found the leak. it was my intake gasket blowing out. i do not recomend the felpro 1257 race intake gasket. here are a couple of pic's.
got it replaced with a felpro stock type gasket now.
hopefully taking it to the track this weekend one last time. i will bump the wastegate to closer to 9 psi. look out here come 13's. tom
