went for a cruise today after about a month, and couldnt hear my wastegate screaming while i was boosting, only realised after about half and hour that i was running like over 30psi of boost ( showed on the gauge) boost controler is ****ed, now what i wanted to know is when a gtr hits boost does the oil pressure just ride to about 6kg/cm3 or does it raise up then go down as the revs rise, as my car was boosting and at about 6500rpm the after market oil pressure gauge was showing that the pressure went down, so i dont know if thats good or bad, anyonw have any idea
