So at idle I'm sitting at -9.2 . Now, with the car on but not running it should say 0 but I'm at -0.8 so the formla can be adjusted in evoscanso you read 0 with key on. So really I'm at -8.4. Depends on your elevation I think.

 

Great! Thanks for the answer Piper, I really appreciate it!

 

With an autometer boost gauge stock turbo about -15, now with AEM boost gauge with x turbo on my RA its -23

 

-15psi at idle! Holy turd, thats twice what I am getting right now. Why is that? Piper and I are spot on 8.5psi at idle, I have never hit -15psi, not even in sport mode after letting off pedal. Hmm

 

im sitting at about -10 with autometer gauge...and apparently im only getting about 5lb boost :/

 

I pull anywhere from -18 to -23 inHG

 

I get -18 -19 inHg. That is with an AEM boost gauge.

 

-8 or -9 PSI at idle with GST basemap v2 and ProSport Digital Boost Gauge

 

I'm curious why you are so paranoid about your vacumm pressure at idle? It's one thing if you arn't building proper boost to troubleshoot a vacuum leak but if you arn't having any issues why worry?

 

SOG_RA no wonder you have over 700 posts

Around -8 PSI is what I remember having. Tho I don't have any log with me at the moment.

Did you notice any problem with your car??? Why are you stressing so much about it?

 

im seeing about -15 at idle and im getting about 8psi max boost right now...checked all clamps etc...and seems ok. boost/vacuum leak somewhere?

 

I had to replace my vaccum hose the other day and hose wall was a little thicker then the stock one. My question is what clamps should i use, i seem to have lost the other ones.will any clamps work and how tight should they be

 

Thanks for pointing out I was "trippin" every answer I got was from a 9 or 8. Simple question.simple answer. Thanks to those that answered even though its a dated thread. For last question, the thickness is fine, just better quality hose. You can get vacuum hose clamps at almost any auto parts store. Get the assorted bunch. They are the same as what came stock.

 

i will log my ap tomorrow and i will tell you what i have .... not this makes me wonder.... hrmmm i remember seeing - 10 psi today but im not sure now... lol

 

I just put in an AEM and it shows around -16-18 at idle.
