I recently came into possession of a 05 gt manual. It has an airaid intake (I think, haven't looked in a while) and flow master cat back, nothing special. I know it has the smaller intake that doesn't require tuning and its still on 87 octane. I am purchasing 4.10 gears and a clutch pack rebuild and am debating on getting the Jlt series 3 and bama tune with 93. Is it worth getting a new intake with the bigger maf housing, or should I just get the tuner and 93 tune and tune on this intake. Thanks for the input
