STi8 with TD05 20g no power until 4750
Car has standard engine and intercooler, apscaik, ported headers, custom inlet pipe, td05 20g and Andy F ecutek.
Up at Andy's car produced 380bhp and 351lb ft. Car felt superb until I got home and I now am getting no ***** until 4750 @ 1.5bar.
Can't understand it a,m getting 1bar @ 3250 but car doesn't seem to want to pull until I get near the 5k mark.
I have checked for leaks and can't find any I am at a loss
I hope to do more checks when the roads are a bit quieter.

I am indeed Chris
I tend to suspect the turbo as it was one of these replica 20G's that Alan got cheap from a mate. Its not a genuine Mitsubishi turbo as far as I could see.
Have you checked the intercooler casing crimps are OK Alan ? Those boost spikes that you had on your last turbo may have caused it to weaken or crack ?
Difficult to diagnose without seeing it, did you do the boost test I mentioned via email ?

I am in the process of getting an avcr with the hope the problem will be sorted with that.

You need to identify what's happened, such as a split boost hose.
