First here are a list of my mods:

VF34
vishnu uppipe
godspeed downpipe
apexi catback exhaust
samco hoses
dawes MBC

I am waiting for the Utec for EM along with injectors and fuel pump.

The problem that I am having is that I can't turn down the boost. In first and second, boost seems to be fine holding at .8 bars. In third and fourth around 5k rpms boost goes where it wants...somewhere around 1.2-1.3 bars and I hit fuel cut due to overboosting in the top of fourth. I have tried to lower the boost all the way down but still have the same results. I tried a hallman MBC and still had the problem. I even tried without a MBC...just the stock hoses and still went somewhere around 1.1-1.2. It seems that my stock boost gauge is reading correctly because it read 1.2-1.3 and I did hit the fuel cut. I can not figure out what the problem is. I have searched and still haven't found the answer. PLEASE IF ANYONE HAS ANY SOLUTIONS PLEASE HELP!!! Thanks in advance.

injectors and fuel pump would be the cause?

Wastegate stuck closed? Some have said that the wastegate rod can be bent and doesn't allow the wastegate to open freely. Best to check operation...
