As in the parameters to set that particular code, someone else may be able to elaborate on that one

As in the tolerances

Is the car ACTUALLY overboosting? Have you got a boost gauge on it? If not, that's your first point of call!!

After that...

Yes, ported wastegate can help but only if the tune is setup correctly.

Hmm I'll get it all sussed out on Saturday going to the tuner Saturday morning and spending the day on it till its right... Any more info is great though as I can pass it all on and check it out

Try again, I deleted some stuff

ok so had the car tuned again today, improvement in performance again but no go in fixing the issue with the DTC

this guy has tuned HEAPS of BAs BFs n FG turbos and my car is the only one hes had this issue with.

to make the problem even more confusing as soon as the out side air temp drops below 20degrees is when it starts boost cutting and throwing this dtc, when ever its over 20degrees out side I can thrash the sh*t out of it non stop and it wont fricken do it!!

im convinced its a mechanical issue with either the IAT sensor, Wastegate actuator or the Wastegate solenoid.

what do you all think???? :( :( :(

Just replace all Of them simple and not that exxy

think your wasting money replacing parts with out testing them or data logging

we did data logging today but it was hot outside and the car was running fine, till this afternoon now that the temp has dropped 10degrees its playing up again.

come to think about it the MAP sensor was reading 150kpa lol which worked out to be about 27psi but it was only running on 13

looks like ill be throwing a map sensor in it too :-/

You have either 1 of 3 issues or possibly a couple combined

Your tuner does not know what to adjust

The HP does not allow correct turbo control

Your wastegate is not controlling the boost correctly, but either of the above can stop this from setting the code

still believe one of these to be your issue
