dual stage boost controler? how many lbs
 

Hey everyone, I am ford nut but also have grown to love my wifes xt. I been bugging her to let me mod it just a little bit, so i am looking into a boost controler, boost gauge and filterw/silencer removed. I was wondering what kind of boost can I push b-4 i would have to worry about a lean condition. I was thinking since stock is 11.5 , I beleave I would go up to 16lbs prob give me another 40hp.

granted I am new here not to famliar with subaru mods so any info would be great.
