I'm getting ready to change cams and exhaust and change from Fuel Pak to SEPST. I've already purchased the SEPST (32109-08B) and don't know if I need to buy / have the cables and software, or is this something that any dyno tuner already has? Are the cables and software just for me if I want to tweak something from home? or do I need to bring them with me when I get the bike dyno tuned? Thanks for the help.
Take some sort of flash drive with you and ask the shop's dyno tuner for a copy of your map when he is finished. That way you'll have it if you make a change and use another dyno tuner in the future.
The shop should have the disk and cables. If not, leave and find another dyno tuner.
