Hi,
I've been searching and can't find a definative answer for this, so here goes:-
I have a full decat, and a AEM Truboost controller on stock j-spec tubbies. Now, I know max boost on number two is 1.2bar - but even with my wastegate crack pressure set nice and low, (about .1bar!) I get a max boost of around 1.28bar, but watching the boost gauge it seems to be sustaining around 1.1 - 1.15bar - obviously with a spike of over 1.2 somewhere, but the main bulk of the actual boosting is under 1.2 bar.... now, is that safe? Can I up the boost so the sustained level is nearer 1.2 bar, and I ignore the max boost as it most only happen for an instant??
