I dunno but the guys at Anarchy have always answered my questions like immediately and I am not even a customer yet... Far as I can tell they seem to be standup guys backing up their sales and service. Peeps gotta work with them though. I don't have a problem with what they are doing and plan on buying a V2 and some tunes just waiting on getting the twins plus the injectors, cam, etc etc before getting the new tunes. Is that a problem using tunes and a V2 when I already have tunes from another tuner via autocal? That autocal seems to be not functional so what needs to be done to go with some new tunes with a V2?
