ECM reflash before or after tune?
I bought a Dynojet Power Vision tuner and will be installing a "Stage 1" air cleaner for my '14 XL1200V this weekend.
My mods are light (pipes, XL-VIED-14 and the air cleaner), but HD recommends ECU reflash w/ those types of mods.
But should I tune before or after the ECU reflash?
