recently did up-pipes on my 2002 f350 and when i had the turbo off noticed it had 1.00A/R on the housing.from my research i've found the factory used a .87 A/R,would the difference in housing size explain why i only make 17-20 psi of boost when i accelerate hard,been told i should be making more than that.have a edge evolution set on 100hp(bad tuner but makin it work till i can afford a good custom chip) the edge reads through the OBD port dont know if that has any influence or not on my boost readings

Were you looking at the intake or exhaust housing?
