Who has tried both of the higher hp tunes from these guys? I know KEM and spartan has been around for a while. I have a h&s right now and don't really want to get the spartan tuner. Can the spartan tunes be loaded onto an h&s via mcc? I do town driving and pulling a 12K horse trailer. Always have pulled on the street or performance tune if its just flat hwy cruising.
