And since the profec's default settings are about 14.5 psi with average "gain" and "set gain" I have a sneaky suspicion youre going WOT in first gear and spiking like a motherfucker.
Change out the valve cover gaskets.
BTW, what else does it have on it if youre effectively maxing out the boost on a t28?

I bet he isn't actually boosting to 20, I bet he is getting to about 12 psi but has a bad leak and he doesn't have the correct vacuum... since his gauge is missing 16ish on the negative side...
his gauge is lying to him telling him he is getting madawesomesuperboostyo... when he is only getting stock boost...with a nasty leak... which means his car just smells like gas...
