After running MBC's for years I thought I'd go back to stock boost control for simplicity sake, however I have an overboost condition.

I am running a 2.5 Mopar Performance SBEC. All vacuum lines are new, and I am running the requisite restrictor in wastegate line.

I assume that the fact the rest to the setup is not stock - +1mm bigger valves, Super 60 turbo, 3" s/c & d/p - impacts the computer's ability to control boost?

Just wanted to confirm/get general consensus before I start chasing an issue that isn't.

Thanks.
