i have a 94wrx de-cat big bore exhaust arc air filter dawes boost controler boost is set just under 1.0 bar when idling guage read about 55 on vacuum side and when leting of accelerator going down hill goes to about 65 on vacuum side seems very high to me what would create this vacuum to be high any ideas

 

My vaccum on my 93wrx is the same -65 so I wouldn't worry about it
