So I've been battling an issue with what I believe to be the fuel cut. 1st gear cold start will boost ok. After that max boost 2 psi then falls on its face. Replaced the map sensor ( which was wildly expensive) and no change. Scratching my head at this point. Would a boost leak cause this and if so would it be within the boost track or exhaust side? Thinking about deleting the stock boost controller and seeing if I have an issue with that that will not code. Any ideas or direction would be greatly appreciated.
