Hi folks just a quicky. I think i have a boost leak after having a remap on for a few months. Currently im only hitting 5 psi boost and getting -22 vacuum. Sure i remember that vacuum should be about the 15 mark or you do have a leak but can find the info anymore. Anyone give me their boost gauge readings or know the levels that it should be?

Thank you in advance

On full throttle my boost is about 20 psi and when idling my vacuum is about 20 and when moving on road in gear with the pedal not being pressed is about 26 or so, not sure if mine is right though...

5PSI is limp mode.

yea mate but should have said that its def running more than the 5 psi boost its showing as have the old limp mode prob sometimes on cold start up (ok after knocking ignition off/on) and i def have more power than when its in limp but not as much as i did up until a few weeks ago. Im thinking its a n75 issue but really dont wanna buy a new one and find it dont solve the issue. Going to reverse the dv as the pipe is rubbing on the engine cover and do some pipe checks and the n249 bypass and see if any of them help.
