For these EFI engines... spinning the air before the TB is a total waste. Port injection stoich begins at the cylinder 'n it doesnt matter what the air's doing after it goes thru the TB. You can 'distrubute' whatever you want... but these spinnyfan things are junk. You say 'noticible gain'? You have a Notary certified dyno sheet from an independant tuner to prove that? 1/4 mile timeslips? No? I didn't think so. Take your Spam elsewhere.
