how is 380-390 bhp made on a 4.8 i thought it was a bit of a struggle on a .63... What are the Driving differences of a .48 and a .63?

What rpm do you spike to 2.3 bar? and what actuator are you using? personally i like revs and would hate my power/boost to drop off after 6,000rpm

Turbo only lasted every 12-18months
Where could i get my head ported and polished?
