your turbo wont put out high PSI when in neutral mate you need to be on the road driving.

then the turbo will spool up and create some air pressure and when u let off the throttle the dump valve will release the air to atmos.

Got a Bailey dv26 on mine and I can't believe how loud it is (had many a compliment - and a few funny looks from my older neighbours)
P.S. rwy'n dallt cymraeg yn iawn!!
