First I'd like to say I'm a new Harley rider and just learning so anything you post will help me and I need all of the help I can get. I'm considering putting Basanni True Duals with MegaPhones and free flowing air filter kit on my 2005 pure stock fuel injected Ultra Classic. First I'd like to hear from anyone running this combo. I'm also considering tuning it myself with a DTO, Has anyone on here done this as well and how did the bike run afterwards, popping, rich, lean, MPG change, noise level and any other noticable changes you encountered after making these changes. Also I'm a little confused about one thing. Can I run the stock Harley software and simply add and adjust out the DTO to iron out ALL the tuning problems? Or do I have to use the DTO as a fine tuner after a Harley dealer downloads a program into the engine controller? Thanks in advance.
