Awesome, thanks!

Well isnt it interesting what you find when check your work...I didnt hover over the tuner while he was doing his work but now going back over his logs I see some interesting information.

Most interesting is that the Dyno was measuring a max of 11 psi boost. However loking back at the logs I was getting a heck of a lot more than that...up to 23psi!?

Looking at the logs I see boost ramping up rapidly, up to 165 kps (23 psi, 1.62 BAR) at 4200 rpm! AFRs are 11.5:1 and ignition was massively retarded at 4-8 degrees btdc. That would explain the dead Innovate 02 sensor...must have burned it up!

That looks like a "smoking gun" to me. The dyno's MAP was way off (Maybe it was calibrated for 1 bar, not 3 bar?) and ignition was also off.
