Ive had a suspicion that ive had a boost leak for some time now. Today was a good day and I did some logging. Anyway, I found that at idle my relitive manifold pressure stayed at about -10.5 PSI but my boost guage reads -20 PSI. Now its my understanding that the wrx should stay at -20 PSI at idle. Am i mistaken here? Also I did a third gear pull on the interstate and my boost maxed out at 13.06 PSI with a WGDC of 94%. I know i should at least be doing 16-17 PSI. So would this indicate a boost leak?? Is there anyway I can upload the logs to here?

Yes you are mistaken.Take a look at that boost gauge a little closer.It is not reading -20 psi,it is reading 20" of manifold vacuum (inHg).What gauge do you have?You might be able to go on thier site and download the users manual to help explain how to read it.
ROFL ops oorme:, Its some lil cheepie that came with the car when i bought it. Im looking to get some prosport here soon. I take it roughly -10 PSI at idle is normal as the log would indicate?
P.s. I did some searching on teh googlez and I think I understand a lil bit better lol. Ya learn something new every day.
