I must check. I’m not sure mine is getting that much.

Check the ECU red plug, if it's full of oil you have the answer

I'm pretty sure mine's not.

Thanks Sierrafery. Unfortunately the red plug is as clean as a whistle. I was rather hoping it'd be oily as that would be an easy fix but, alas it's clean...

Today I'm gonna change the boost hoses and see if that makes any difference. Failing that I'll try running it without the air bleed valve and see how it goes. Failing that, I guess I'll be doing the injector seals again.

When I take it for a run later I'll stick an SD card in the Nanocom and record it all and see what it shows up, if anything.

That's something I haven't checked yet but I will tiday.

Hmmm. I can only get around 1.1. Coupled with the hissing noise at around 2300 rpm I'm thinking that I have a significant boost leak. Hose replacement time methinks...

The MAF is also reading low - around 47 at idle rising to about 350 at full noise.

Operating temp. fairly steep climb, full noise, best mine can manage is 0.87 bar. And yet it goes reasonably well... Hmm, I guess a fe tweaks might surprise. No play in the turbo shaft etc, so some checks might be in order.

Sorry for the hijack.

Quick tweak of the wastegate and I have 1.15
