Besides loosing fuel repsonse on running one, is there any way i could get it tuned to not run rich even though its blowing out metered air in the atmosphere.
This! I was going to say you need a blow through setup to run a BOV or bypass valve that vents to the atmosphere. Repd!dude you can't cheap out on this one. to get that "cool blow off sound" you need to run a blow through setup. chances are you'll get sick of it after a while anyway. it's not like a turbo, you get a constant hissing ALL the time because the blower is always spinning.
