I have a 2014 Vmax . Looking to put on a delkevic exhaust that is a cat delete. I have a K&N filter that I will be doing the air box mod. I have the exup valve servo eliminator . Do I need to purchase this Dynojet Power commander to make my bike run better? Is it easy to set it up myself or do I need to take it to a mechanic? Thanks for the help!
