its been two days i am trying to solve this problem with no luck yet so here we are...
lets say on 3rd gear (or pretty much any gear) when i put my foot down and the revs start building to around 4000 rpm the boost goes up to 0.9 bar and then immediatly goes down to 0.4 or 0.5 and stays there till the rest of the rev band.
I tried the N75 and mbc in parallel and still the same prob. Done a pressure test and tested good.
The turbo looks in good shape.
Car have a relentless exhaust manifold and downpipe, 007 DV. AMK engine.
Do you think a crack in the manifold can cause that problem? Boost holds 0.9 bar for just One second!
I disconnected the maf and tried again..same result.
i am out of ideas here...
