Hey guys I have a 97 gtp an I'm having some boost problems it's only showing 4.4 lbs of boost on my gauge an my torque app an I can not figure out what is going on with it I've looked up the vacuum diagrams an it looks right an my bbv is hittin the set screw at the very bottom when reving the car an goin down the road an I have no leaks anywhere that I can find the only thing I can think to change now is the map sensor should that cause boost not to show if it's bad I'll list all my mods at the bottom thank you guys
