Turbo used in Powerstation stage 4

Hey guys do any of you have any info on the turbo used in the stage 4 powerstation kit. They say its a hybrid turbo and I was speaking to them they said it only spools up slightly later than the spec c standard turbo they also say it is goo for close to 400bhp thats on uk fuel so I am sure on our fuel on a spec c it should be good for at least 360bhp.
Let me know what you guys think.

Its an AET turbo as far as I know.

Our fuel with half bottle of lucus is as good as most of the uk's high octane stuff As fas I know!!!
Are you getting the work done over there?
