Random boost levels, negative LTFT, and tons of vibes

I saw the Shoutbox where you said you had a crack in the OE housing? My coworker also has a speed 3 and he may be willing to sell you the turbo and or housing for super cheap since I gave him my BNR S1 after I upgraded mine

 

It depends on the price, because my idea was to drive around for a month until i got an BNR S3 or S4, how much would he want for it?

 

Hey, just wondering if you figured out the issue with your car? I have a problem with mine that sounds very similar to what you described.

 

Nope, Car is still down.

So far i have checked:
Turbo
MAF
MAP
O2 sensors
Gaskets
FMIC Kit
Intercooler
Injectors
Smoke test
Boost leak test
Wiring
Tune


It's been to about 4 shops now, all with the same answer "The car runs fine except for the boost issue, we cannot figure it out without charging you (insert insane number here) for a deeper diagnostic"

No one has been able to actually diagnose it. If you figure it out please let me know or shoot me an idea of what to check, next i'll be looking into my timing.
