Hi there all Can anyone point me in the wright direction I've had my new engine in now 2 months and its been goin well so thought now all done time for a little tune up it was boosting about 18 psi and to me that's higher than standard anyway but turned pump about 30 degrees ish and the boost has gone up to about 19 just over and hasn't made that much difference so want to turn pump maybe same again and then crank the boost up with a fmic but how fare can I go with boost till too much air to fuel just need pointing in wright direction plzz thanks
