Just bought a 2013, and I have a couple of questions that the dealer could not answer. When you put the GYTR (FMF) muffler on, is it necessary to change out the ECU at that point and remap? If the answer is "yes", then do I need the Power Tuner or can the dealer do this with his EFI Controller? The dealer does NOT have the Power Tuner. If needed, I would have to buy one.
Does the dealer have to reprogram the air/fuel idle mixture for the FMF pipe?
Thanks in advance.
