1.32 bar of boost, dropping to 1.2 bar 475bhp 390l/bs @6900rpm.

That's very interesting.

Are you sure you've GT28's?

I only ask as our spec's are similar, but you have bigger turbo's, injector's and IC, and you make 5 bhp more, but 30 Lbft less torque.

did a few little bits to make it to 408bhp. port matched my plenum and exhaust manifold to improve flow, fitted the baffled twin turbo pipe,

but yeah made up with the power i got on the dyno day. 408 bhp with 320 ftb torque :D
need to upgrade my fuel system next and get rid of the ceramics
