Doesn't seem to have belt slip if it was slipping it wouldn't be boosting the same.
Injectors were flow tested which was stated above.
Haven't tried disconnecting the battery, but the ecu has been reflashed several times with HPTuners, so I don't think that would make a difference.
And I can't remember which fuel cleaner I used, but if fuel pressure was off I would think we'd see a change in the af readings, but they are staying consistent around 11.8-12.2 at WOT.

Okay....so mathematically you cannot lose 50 HP with small drop in torque that you experienced as long as your rev limiter is set at the same point and you are running up to that point. That's what set up a red flag for me.
So a few questions;
1. Might sound stupid, but did you dyno in the same gear as the time before?
2. Is there any way that your have any drive train issues above a certain rpm?
The reason I bring this up is that, I assume that you're running the engine up to your usual point, and the torque is close to the same, but what if you are not getting the proper relative wheel speed at said shift point?
I'm just trying to add something, everyone else has appeared to touch on most other probabilities.
