Well got a new gauge on the way. found my vac leak where my gauge tied into vac under hood the 90deg. elbow had splits and cracks in it. so got a new one, installed gauge and now i get 16# of boost which it's up 1#because the new gauge is screwed. so i will have new one tomm. but as far sas the mod i am set back to bearly touchin and this mod works. i see what your sayin now thanx for the help. i am still gonna look for leaks because the 90deg. elbowthat was bad is only 8months old so i wonder how many leaks i really got!!!
