I have done a lot of searching on this topic, but I really couldn't find the answer. I'm sure it is here, I'm just not the best at searching yet. Anyway, I have an 05 FXDCI with Slip-on mufflers. I want to add a high flow air cleaner, probably a Sreaming Eagle one. I have no intention of doing anything else to the engine, such as a 95" build, cams, etc. My question is, if I don't plan on any more upgrades, why should I not just have the dealer reflash my ECM for the Stage 1? I realize that the SERT has more flexibility, but since I plan on doing nothing else, I would rather save a few hundred bucks and spend it on other things. Any advice?
