ecu or boost controller asking for say 1.2bar and unable to keep it to 1.2bar usually at the top of the rev range as the wastegate is fully open but not flowing enough exhaust gas away from the turbine.. so turbine spins faster and produces more boost than required..
usually on the newage sti's the boost creaps to 1.4barish which is not overly a problem as you want it to be running that etc.. but means you cannot say have a lower boost setting because asking it for 1bar sees 1bar to 5500rpm where it then boost creaps to 1.4bar..

Your choice of exhaust will also dictate how bad the creep can get.
I can't see a different actuator helping help out with creep though.
If you've got the opportunity now, port the hot side by making the wastegate hole bigger and open out the lower part of the mouth going into it.

yes now im understanding it better when desired boost is reached the wastgate opens so as to control the boost or stop it climbing higher
porting helps even more more by helping to flow faster so as when fully open it is enough to stop the boost getting higher

You could smooth out the turbine entry, match it to your up-pipe, or at least make sure it's not smaller. I did that job on my TD05 with some cutting bits and an electric drill.

the headers and up pipe have been ported by harvey before i bought and the up pipe matches the turbo at about 47mm
aet turbos offered to port the turbine housing what does this mean ?

And some people just like doing stuff themselves. There are many places around the country where finding someone to port a turbo for £50 is much harder than having a crack at it yourself, if you have the confidence and tools to give it a go.

Nah, he'd loose the early spool..
In fact it would be worse that a VF34 as it wouldn't have the roller bearings to compensate..!
Now, if you could fit a ported P15 hot side to a VF34 roller bearing core/compressor that might be interesting. Anyone know if this is possible..? Surely the spool would be even better with this combination, 1.5bar <3k should be possible ..?
