i've never owned a turbo before so i was hoping someone could help me out a little..
im running a completely stock 34 gt-t and sometimes on ignition the boost gauge won't move, not even a slight fluctuation, today i was driving and the gauge had been sitting on nothing, then doing 60 it suddenly jumped to about midway up the gauge, stayed at that pressure for 10 seconds, then dropped disturbingly quickly back to 0, im not sure whether it's because i've only started looking at the boost gauge while driving that i've noticed it goes for ages without moving from 0, i can hear the whirring/spooling? sound but without gunning it, cant tell wether it's active. i had a major service (smooth garage) and immbolizer installed friday if thats relevant at all..
basically i'm dumb, is there something wrong? or is that normal behaviour? only just bought it, i'll be pissed if it's already playing up. is my best bet getting a compression test?
cheers guys
