as some of you may know i have been having some issues with no boost coming in from my second turbo through 1st to 3rd gear its intermittant, so some times it works and some times it doesnt, which is really starting to annoy me.
I have checked pressuer drop accross the FMIC and everything is fine,
I have checked that all vsv are operational and they are.
Checked all pipes related to the turbos and no cracks, splits, or kinks.
so the only other thing i can think of is a hairline crack in the manifold its self, as i have seen this mentioned a few times on here.
Would this crack reduce boost levels or even stop the boost from coming on line from turbo 2. Or does the crack more commonly happen on the first turbo.
