Nistune is gonna cost you $500+ with all cables and software (otherwise why get it if you cant tune it fully?)
It would have been wonderful in the days where the only ECU available was JWT. But now, with Calum gone, I think its the only tunable option anyways if you dont wanna compplicate yourself going Honda or Standalone$.
I will hold to my Calum RT v0 for the longest time, even more if Dave comes with tunercode for the B14
