65 KPA is almost 9.5 lbs of boost. Do the boost bypass and see if it goes up, if all else fails take it to the dealer Joe.

the boost bypass mod is only if you have an aftermarket pulley. u do this mod only when u are running more boost (12.5+). it prevents the boost from being leaked outta the system. this mod wont do anything for a stock pulley. also, altitude plays a major factor in boost.

Well I'd think they would have to put it under actual drive conditions to prove if it is getting proper boost or not !
