right now i just have a stock boost gauge and it reads alot lower then it used to,i knows its not accurate.but it started showing lower boost levels when the car started acting weaker.i have an Autometer boost guage that isnt put in yet,when i ordered it they gave me the wrong one (i think) it shows no vaccum,only + boost from 0-35 psi
also how do i pressure test the entire intake system?

Get Robbeck's pressure tester. Its a great $40 investment. You have a major boost leak if your stock gauge isn't pegging the top...i think it pegs the top after 7 psi.
Until you get his pressure tester, pop the hood and listen for any obvious leaks. Check around the throttle body, visible Intercooler pipes and the inlet pipe on the turbos. Make sure everything is tight and you cannot hear any leaks.
