Needle valve would be in the cab, not the dawes. I would increase your max boost more via dawes, and then wind in the needle valve a little more to increase spool up. Just remember. If you raise the dawes pressure and dont adjust the needle valve to suit your spool up will be slower. The two adjustments are relative to each other.
Awesome replies guys, thanks very much.
I'm away at work at the moment so can't play with the car till Saturday.
Will have a bit of a fiddle then.
Still learning the new beast and looks like I will be for a while yet :)

Ive got mine set for a smooth power delivery pulls quite hard for a big heavy truck. My boost is at 15 psi at 2200.and by 3000 it has hit 16psi. Every car is different. You will know when you get the sweet spot. When i was setting it up it was adjust and drive. I found setting the dawes valve for max boost 1st, got that set and then just keep opening up the needle valve in small increments at 80ks my egts are at 220 and on long climbs it gets to 420 and thats under full boost. I do ha e a 3" exhaust and a snorkel and fuel consumption is around 13lph. Hope this helps
