945T engine stumbles under boost and maybe missing when accelerating

OK, I changed the hose from AMM to turbo. BTW the MTC hose that I got did not fit 100% It seems to be a little too short but it fits after some elbow grease.

Anyway, after the engine was warmed up, I accelerated hard. Turbo came in fine, car idled fine and I was real happy. On my way home at a traffic light, I nailed the accelerator, turbo kicked in and all of a sudden the engine bogs down. After that, I noticed that the engine was missing, turbo would barely kick in. Sounds like a vacuum leak?? Any ideas where to look?

The turbo hose seems to be connected ok. BTW in the middle of the turbo intake hose, there is a smaller hose that is routed to the intake manifold. What is this hose for? Will that cause a vacuum leak??

Your assistance is greatly appreciated.
