Well Dustin here's what I get from reading your recordings, you have an EBP of 47.99PSI and EGR duty cycle of 54% and hardly any boost with fuel being cut back, so here's what I'd do if I were you. Start from scratch, barring the fact is you're pretty sure the exhaust isn't plugged, you must have something causing that kind of EBP pressure and that only leaves the turbo and the pipes to the heads.
