I have a 2015 fzs stock with only mods of riva ribbon delete, riva power filter, and candoopro gps module. Would consider an ecu reflash but I do have the extended warranty as I was concerned about the timing chain problem. I would be interested in having my ski running the best way acceleration-wise and top speed to 75 or so with good holeshot. Would the level 1 or level 2 Dean's reflash be desirable without jeopardizing the warranty if I had timing chain problems down the road? Is this worth considering? Thanks for any information.
