power boost valves can be used to increase fuelling. so you need to be running weak for it to be any good....

maybe with a high spec rebuild including headwork cams increased revs and so forth it would be useful to help compensate for increased fuelling..

ai, 3.0 bar of fuel pressure was fine on my turbo on low boost at 217bhp, so anything above that and u need to up the fuel pressure
