Had to turn mine down a bit as it was spiking up to 1.4 bar not so good, now peaks at 1.25bar I'd say it is holds boost above 1 bar all the time. But am currently having some occasional poor response and surging issues so I might turn it down more, but these are hopefully fuelling problems due to a knackered fuel pump I am getting a new uprated pump soon hopefully sort it out. What I need to do is have someone monitor the air/fuel mixture while I give it some welly, see the mix goes weak when/if it goes wrong. Easier to have someone else do that instead of me trying to watch the computer, the boost gauge, the rev counter AND the road all at the same time
