1:from my understanding both can have custom tunes downloaded
2: where is the best place to buy it from and whos custom tunes are truly the best (ive heard nothing but good about matts srl tune) and also some girl named vivian, im not looking to race my truck but i need the power when i want ya no, i tow quite a bit and my job requires alot of travel so i drive close to 5k a month, i dont purchase my own fuel either
i have an edge insight so i dont need the livewire i believe the only difference between the two are the x3 doesnt moniter anything??
so if anyone needs to correct me about the x3 or the livewire please do and please let mo no about custom tunes i am ready to pull the trigger on a tuner asap
