Yesterday I replaced My stock old and dry vacuum hoses with brand new BMW ones..First I unplugged the stock Pressure sensor(N370)harness to get at the vacuum line going to that..redid everything and now the stock pressure gauge stays at 0 all the time..Even on throttle with a load the car reads 0 ..I have a full RB exhaust installed with no FCD and it used to cut before i installed the new vacuum lines but the stock gauge would still show me the boost and go over and under 0 ..whenever i throttled too much overboosted the stock fuel cut would kick in about 4000 rpm nothing serious..Now after installing the new vacuum lines it always stays at 0?!and the boost dosent cut even when i step on the gass all the way....Like a magical FDC but I didnt install it yet since its comming from japan?>!@@!!now im afraid it wont matter if i install my FCD since the stock pressure sensor isnt working it dosent CUT fuel anymore ..would that be my problem??@#!!whats wrong with it??i checked everything and reinstalled new vacuum lines again and i still have the same problem..Did the stock pressure sensor short circit while i unplugged it and plugged it back in??are they that sensitive?!@# WTH..STUCK AT ZERO!! 0 could it be the stock pressure sensor blew while i replaced my lines??!!someone help me out..
