Dissapointing performance

170 psi is pretty good. Did you check all 8 because I think you will one cylinder that is way off. Your combo should be a lot stronger than it is.. If you keep saying everything about the tune is right then I have to believe your engine is wounded or the cam phasing is not where you think it is. J.Rob

I think he might have a problem with the cam phasing. I have seen where changing the phasing from 4 adv to straight up to 4 retarded change cylinder psi. from 165 to 195 and totally change the characteristics of the engine. 4 advanced a bottom end powerhouse and 4 degrees retarded killed all the bottom end. He swears the cam is in right, but that he has a fair amount of chain slack. so....... Just one of those things where a guess just isn't good enough.
