I fitted a boost gauge today - I was expecting there to be essentially 2 stages of boost on full throttle - inital overboost, then a constant held boost as the revs rise. However whilst the turbo does overboost, the "held" boost actually gradually falls as the revs rise - i.e. it doesn't hold the boost at all. It never falls below 9psi (its a TMS stage 1), but after an overboost of about 13 psi, and an inital held of about 11-12, this further falling makes the power delivery as the revs rise slightly flat. Anyone know whether this is normal? Many thanks Charles
