Unhappy 2007 WRX issues. Would a Stage 3 OST hurt?

I know I'm boned, but curious as to just HOW boned.

2007 WRX - 30k miles on motor
ProTuned by National Speed 2 owners ago and doubtful that the car hasn't been messed with since then.
STi TMIC
VF48 turbo
840cc injectors
Injen CAI
Invidia N1 2.5" TBE
Hallman Pro Boost Controller
Battery has voltage, but low CCA

Replaced spark plugs and Cylinder 3 Coil.

Sorry in advance for the long post.

I picked up this car sight unseen on some very bad advice.
The car was overboosting and throwing cylinder 3 misfire codes, hence the coil and plugs. I turned down the boost controller and eliminated the CEL for Wastegate and Misfires. No CEL for 2 days now.

The issue now is it's still missfiring, but not throwing any codes. If I baby the car, I can putt around town ok, but the moment it's under load, the turbo spools insanely fast, but the car starts lurching and not wanting to go. It's extremely inconsistent, but the acceleration never scales with the boost.

I put my data logs in dropbox. Here's the link

It's showing some serious knock. I haven't done a compression test or a leak down test yet. Is it shot, or can it possibly be tuned out?
