Ok. so ive searched hours on this for the correct vac number for the 1.8t. cant find it...anways i sit about from 22-25 at idle usually closer to 25. Just wondering if this is normal or if i have a small leak somewhere. Thanks guys.

If you had a vacuum leak, your vacuum at idle would be closer to zero, not further from zero.

If you've got 25 In. Hg at idle, you're in good shape.

elevation plays a big part too. when i lived in tx i had 21 inHg, driving through el paso and new mexico it went all the way down to 18inHg, and now its just under 22inHg here in california.

Also have to compensate for the A/C, if it is on then the readings will be lower... Turn it off and you should get a higher vac...
