Dumb suggestion time. Why not just whack a standard cat in there. That should drop the boost a bit wouldn't it? 

 

Heres part art one of splitting the housing

 



Thanks for this link. Looks pretty straight fwd on page 4.
Think I'll play it safe with this part and run with Jets suggestion. Could do without "Rage mode " if I get alignment out.

Haha it happens but after you've done a few you know how to set them up 

 

the fact is your can is just going to need to be tuned to suit the new exhaust and IWG so bit that bullet and get it all done in one hit and save the frustration :)

Its back up and running with the ported housing. Had the workshop swap the housings over.
I bench tested the IGW75 with the 5psi Spring fitted. The flap cracks open on 5psi, full length at 10psi.
Quick Road test today(too busy for a good test) , gets to 10psi , sits there but spiked to 12psi on the auto gear change from 1st into 2nd at full throttle then it dropped back to 10psi :)
That's enough full pedal till it hits the dyno.
What psi is the factory boost cut meant to cut in?

Once the rod dropped neatly over the flapper hinge part the rod was then tightened up by 1.5 turns from memory which is about 2mm as suggested.
