You can have a internal boost leak.  If you have charged air recirculating back into the intake pre turbo.  Check valves, something in PCV....

But that wouldn't result in losing metered air Sad

Diverter valves are upgraded but I might make a rig to push 20psi to them to verify they are holding up. I have extra pcv valves thats are good so I'll swap then over. Thank you guys for the help. Once again with the problem child cars!

Ps_w!!! My live data(boost gauge) followed it my logged variable for manifold pressure showed different? Said peak 16psi and dropped to 8psi. Hell no, the car hit like 23 psi and tapered to 14-12psi. Looks like I have a faulty sensor. Will get back after verifying.

Thank you nyet for pointing me in the right direction...

Someone installed a 3 bar map sensor and didn't tell me, well no one knew that it was installed.
Time to actually start tuning it now  Grin
Thanks everybody for helping me out.

I honestly don't even know, I'm pissed I was chasing my tail! I hooked a boost gauge up which I should of done from day one and saw it was hitting 23psi! Thats when I'm like this ecu isn't seeing boost correctly. Lesson learned.

I'm in silence, a simple thank you doesn't describe how thankful I am for this action.  I'm going to stop here before you multiply it by two.
