Dyno(PV3), with AA tune, then to get all the benifits, Dalton clutch kit and secondary rollers. An ECU tune requires down time for shipping unless you plan on buying a new ECU. PV3 let’s YOU tune your machine in about 20 minutes. YOU can go back to stock or another tune anytime YOU wish. It can also be mounted as an extra gauge, data log, change tire size in the future for correct speedo, read and clear codes. I personally plan on getting the winter tune later this fall. I believe the tunes are kinda close on what they do but I read AA is the better performing tune, but I have no personal experience with EVO. I believe ALL tunes require premium gas….on that note, we do not sell hardy any premium gas here so it is of lower quality than expected. I was told this from Justin at Black Bear when I was data logging for a tune on my truck, so keep that in mind(he was watching the timing curves). So on that note, I do run RP Max Boost octane booster with my tune(adds cost per tank)…..but I will tell you, AA/Dalton combo doesn’t feel like the machine I bought at all, all around better at everything!!!
