Fueling glitch etc

[Gary2304]

hi everyone i am new to this forum so please be gentle with me if i dont explain this technically correct.

ive got a subaru sti with a 2.35 stroker using a owen developments gbt69/82 turbo which should be good for 660bhp at least with the spec ive got.

the ecu is a plug and play S6

1. car makes 400bhp at one bar which is actuator pressure
2. strange blip in fueling between 5-5.5k goes lean then rich and then straight line as before ,it does this at no matter what boost pressure you turn the car up to be it 1bar or 1.8 bar.
3.we cant get anymore than 460bhp out of the car not matter what boost we run or ignition advance etc

ive tried to explain this as best as i can .

does it make any sense to anyone ?

your help and advice would be appreciated.

Any logs?
May be the fuel pump saturated.

Did you log the fuel pressure?

post a datalog and cal file

And ensure the log contains sensible parameters to see what is going on.
