OBX HEADERS and better response from the new software. The headers are the problem.
I too am having tis issue, my car has a new larger displacement engine and larger turbo on the same headers. I put a .5 bar spring in to quell some clutch issues my new engine gave me and my Porsche waste gate attached to the OBX headers creeps up to 1 bar+. My intercooler and tune can deal with it as long as the clutch can hold it. But I'd rather have a better header design..
