Guys, just installed a boost gauge, what vacuum readings are you seeing at idle once the car is warm?
How bout boost readings from a 951S with the weltmeister chip set?

I'm seeing 14 inches of hg at warm idle. Haven't gotten boost readings as I tightened up the fittings after a drive and then my bro in law parked me in...

I get 12 in hg but thats with a very leaky TB seal.

12 cold and 15 warm and will pull down to 21 on over-run

12 cold, 17 warm and 21-22 coasting at speed (no throttle, in gear).

Mike Murcia

13 cold, 16 warm, 21-22 over-run. I guess that's pretty normal.

12-13Hg once started, get's to 16Hg-17Hg when fullly warmed up (on idle). Drops back down to13-14Hg with the a/c on

18-20 warm.

Ok, sounds like I'm where I should be. I'm up 5000 ft above sea level, usually will have 3-4 inches less vacuum up here vs sea level, so that's around 17-18 at warm idle...

12-14 cold idle, 16-18 warm, 20+ downhill cruise. I still have a slight leak at TB and at AC damper connection under boost only.
