I should probably have mentioned that I have a boost fooler installed to prevent defueling on the 100hp tune. Per the analog gauge I'm actually hitting 18-20 psi on stock tune. I also have the wastegate line unhooked and plugged (onto an intake coupling clamp stud) to prevent the gate from opening before the spring pressure is overcome. Does that still seem out of whack? Also, 5" silverline exhaust with straight flow through muffler and no cat, so no restrictions there. The EBP valve is unplugged at the pedestal as well.

I can get these readings tonight, took the Expedition today. Do you want CSV logs of both or just screen shots of the gauges?

That is probably why your previous logs seemed off. The back pressure and boost tests require the system to be as designed.

Boost and back pressure look about right for altitude if you are in IL. Oil temp says engine is not up to operating temp yet at time of reading - EBPV (assuming e99 has one) may be slightly closed, should open fully when warmed up. Might want to check that.
Note that your mechanical boost gauge will read MAP, and Torque reads MAP - BAROMETER.
Others might comment on HPOP, IPR, and FIPW.

yeah engine was stone cold, I can repeat warmed up if it makes a difference? From what I think I know (and probably don't) my truck seems to be working as it should, so tunes should be the first mod, followed by HPOP.
