If anything a .63 would make the boost drop more as will make the exhaust less restrictive.
Although running a .48 at the top end instead of a .63 to keep the boost up is not a good idea, just means less effective emptying of the cylinders (so less power) and higher EGT's (so less reliable potentially)
People focus too much on what boost they are running and not enough on making more power on less boost IMHO (not a dig at the thread poster, just cossie owners in general)
I dont see why cossie owners cant accept that needing 2 bar of boost to not even make 400bhp on a 2.0 16v engine is a BAD thing!
