mis
10psi with a bleed valve- had it set to that at rollin rd to slow down my oil comsumption! trouble is it dont always do it. i could drive 40 miles and it might do it once, and then fri night i took it 4 a caning and it done it all night. its not really at max boost, more when im on over run in 4th or 5th then just lightly go back on the throttle, or when i could of selected a lower gear but havnt cos i dont want to thrash it, if you no wat i mean????
