this will overwrite an existing tune then? i have a custom tune done from a reputed tuner who specialized in the s54 e46 application. i gave him my car and he did great work, but i feel like there's more untapped power given my mods. i should be a little over 300whp with afe intake/fabspeed headers/RE x-pipe/arqray cans...no?
i'm willing to dish out a 10+ groupbuy price to see what evolve has up their sleeve. if it's not for me, then i can always have the tuner re install the software he has saved for my car.
i'm in for 10+
