I have a ported eaton case for sale. *Note* Im not selling the rotors TB or plenum, this is a spare outer casing that I used to swap to avoid downtime. Im the second owner of this case and I'm not sure where it was ported at, but I saw a gain of @44 HP after the retune. saw @78 with the a 2.8,port, and tune. I have pictures I can email if you want also. pricing is negotiable, PM me for details.
