Why not a "Auto Tuner" instead of a gen 3.5 ?? I was told by my local HD shop that a auto tuner would work fine for my application. I have a 2010 Triglide 103cc (stock). Would like to do a Stage 1 for now and maybe a Bolt in Cam later.SnS 551 Stage 1 meaning pipes,taking out the guts in the Cat,AC, and then the Tuner.
