Internal exhaust flapper stuck partially closed somehow??
Not really familiar with prochargers. Is it normal for them to not make any boost until 4500 RPM??

It is normal to start seeing boost around 4200 - I'm seeing around 2 psi on the other motor @ 4500. The Prochargers are based on rpm.

So over the weekend I swapped blowers and intercoolers and the problem has not changed. I put a smaller prop on the side that I'm having an issue with and was able to run the rpm up to 4800 but again saw no boost. At that rpm I should be seeing close to 5 psi and running that smaller prop with ANY boost I'd have hit the rev limiter easily. I think I've ruled out pretty much everything. I'm leaning towards an intake leak but how would that go bad from the dyno to install?

There’s no way that the tensioner is acting goofy and the belt is slipping is there? When I had m3SC’s in my BT I had to tighten the port blower belt to what seemed like overkill to get it to match the stbd engines boost. Sepentine Belts, not cog belts. I think you’ve ruled out about everything else.
