The G54B is not a REV monster and the gears are not long in a Starquest, you sould try 3rd or something.
On a side note, the intake pipes got done today, thanks to John, and I can't tell a bit of difference other than the turbo's are a little louder. I was expecting the BOV to a way louder than it is, most of the time I can hardly tell it's vented now.
