Id love to hear why also? I have my personal trucks tuned from him. For 3+yrs and over 35k miles. 25k with twins. I have also taken my dads and 8-9 other friends trucks to get tuned after they rode in mine. Zero issues to date. Some of those trucks had efi live already by someone else but they liked the way mine ran. I will put his tunes up against anyones. Not sayin his are better or best but gauranttee his right there with the other top tuners.
Hands down, regardless of who it is, best tuner u can have is someone that can sit in your truck tuning it or on dyno . Way easier to dial in rather then across country.
