sorry..lol my inbox is cleared now.
whats the flow per lift .100-.500?
Im with IQ, though figure out where u want it to idle rpm wise and where the gears are, like said..u can bleed a ton off with more at .050...but unless its a roller...it'll eat away at the bottom end real quick the bigger u go...and with ur lift/flow limitaion...a flat will get lumpy quick as that .050 go's up.

btw hope ur all having a good thanksgiving
