at that pressure aren't you maxing out the efficiency of that turbocharger? I'll go look at the map but that see where the cush lies. Do you have any specifics on your engine itself? I read your profile but its quite vague to whats done to the engine. What clearances are you running?...ring gaps....type of valve job, valves, where the cams advanced off base cirlce? ect ect
