No. 320hp was on regular to e10. The higher TQ number comes only from E85.
A good read (from PHP):
In other words - don't bother with an intake.
BTW - kinda pointless to be discussing mileage if you keep wanting to run @ 80 mph - not gonna happen the aeros will kill you. NO programmer guarantees
any mileage gains. Be prepared to be disappointed if yer expecting any.
