Turbo Gauge Going Crazy

[KODE]

is it normal that b4 i start the car pic1 turbo gauge showing 0- zero

and after car is running its going down pic2 but only to -0.6

month ago it was before i start a car in -1 and after -1 now it changed

is it a problem ??

thanks guys

Nope thats how a boost gauge is meant to work!! Show nothing when engine isnt running and vacuum when car is idling!

[KODE]

does it mean turbo is working when its more than zero or when its zero ??

thats exactly how a boost gauge works mate....below 0 is vacuum up to 0...then anything above that is displaying the amount of boost being used.....i have aftermarket gauge in psi and thats a lot more accurate from what i have found to stock gauges

Like most have said, it's normal for it to sit at 0 (atmospheric) when the engine is off, and for it to go negative when idle (the motion of the engine literally sucks air into it).

However, if the amount it goes down has changed and you haven't done changed anything (pod filter, boost controller etc), then you might have a leak. Does it still make the same maximum boost? (stock on the 34 is just over 3/4, or half way between 0 - 1) Does it hold that boost if you hold your foot down?
