Hey guys I just wanted to see what the proper vacuum at idle is for a 1.8T. Mine is at 15 now, but when I installed my boost guage it was around 20. I have a GIAC X+ flashed AWP, and a used Bailey's DV. Could it be the DV is worn out or is that just normal?
Thanks!

I also have an upgraded Stratmosphere billet DV. Don't think that makes a difference though. Cheers,

I had an issue like this and it ended up being a small leak at the gauge. Just a thought http://****************.com/smile/emthup.gif

Thanks man, I had a feeling it could be that, I brushed it aside though because I didnt hear any hiss.
So you guys think it woudl be that instead of a DV with a weak seal?
