boost gauge flickering

[shan-747]

hi all ive just put a autometer cobalt boost gauge in my car and it seems to hit 16psi then drop down and go up drop down then it holds on 14psi i have my nads all done so what could i do to fix it?
i was going 2 take the car back to where i got the dawes and needle valve done.

any help would be awesome thanks guys :thumbup:

I'm not 100% sure but I believe it's to do with the spring in the Dawes?

Ok should I just take it back to where I got the Dawes valve done and just get them to pix it or can I do it myself?

is this when the motor is not at full operating temp

[shan-747]

Nah it's all the time

And it does it more in 1st and 2nd gear

[kevin07]

what car motor do you have

[threedogs]

what PSI are showing at 100kph on a flat road

Could this have something to do, with that vacuum dampener (green ring thing) on somewhere on the hoses positioned incorrectly ?

[shan-747]

I called the guy that done the dawes valve and he said its meant to do that. And it sites on 14

[threedogs]

you saying it sits on 14 psi at 100 kph ???

[shan-747]

Sorry it sites on around 11 psi

[threedogs]

10 would be ideal but 11 is ok,
