Thanks Adam, it's only on the minimum power setting at the moment (there is a dash mounted switch to toggle this). In this mode the max boost I am seeing about 10 PSI, so the engine is only making about 300 or 325 BHP at a guess which helps make it feel more sedate and smooth.
I have yet to return to Chris's so he can finish the high power map, this will take boost up to about 30 PSI, so it will be somewhat more lively, though I can lower this in the cabin with the laptop.
Still decent power then, if I was you I'd keep it about the drive ability rather than outright power, I found that 400ish was plenty in the Corsa any more just made it less usable and harder to drive flat out on track. Handy having it switchable though, that's my next stage once the apexi avcr is wired in as the Omex boost control doesn't allow boost in gear and the boost vs tps isn't as acurite as I'd like
