the way i see it:
P0102
Mass Air Flow Sensor Circuit Low Input - DONE
afm was either unplugged or needed clean(as u have done and hence sorted)
PO103
Mass Air Flow Sensor Circuit High Input
ur hitting maf limit on ur tune
i can check it and based on what u hitting can be a few option BUT in all honesty 24psi is pretty much max ur afm will ever see as thata fair bit of air to flow on ur td06
i had similar flow at that psi when i had a td06 and testing things out
kinda maxing the maf and also ur map is maxed at this stage (22.5 i think is map max or thereabouts)
that intake pipe must be really freeing up the turbo or something
why is ur GFB coopst controller not controlling boost to 20 psi like u had said - or did u up the controller - its not a good idea to up it untuned man
P0113
Intake air temperature sensor circuit high input - DONE
related to p0102 ok
P1308 OCV Solenoid Valve Signal 2 Circuit Malfunction (Open)
find solenoid
clean it
also make sure its still plugged in properly
didnt u say this was fixed at gcp? either its broken again or was a lame fix.
either way relook into this
Cleaned maf sensor pluged it back in lol
good well done
in summary there is no need to panic as most stuff is sorted
of concern wud be high boost and untuned running on that said high boost
lower it and fix the solenoid issue and then we look into the tune side later
When i had the P1308 Code it use to missfire in the high rpm, it\'s not doing that at the moment might have a look into the wiring when i have time
