Tune is very worth it for detuned cars but I wont bother with it since don't get as much gain in the AWD. I did do the tune in my huracan 610 but that was only because I knew I would go to a supercharger later so tune cost would be credited to that. Really didnt notice much difference with the tune. After supercharging both my R8's and huracan I'm going to avoid doing it on Evo, my huracan was close to warranty ending when I bought it so didnt mind tossing warranty but I have over 2 years left on Evo. My Pedalbox will be here Monday and can't wait to drive car with it on. Also it's worth spending the extra $50 for the bluetooth model, I got that one for my 488 and then just hid the controler under seat and used phone to adjustWith the tune and The pedal box, that’s enough for me.
