Nothing but great things to say regarding Scott Cook and his team including Jorge Munoz. From day 1 Tapout tuning has been great in helping me create this beast of a daily driver! From quick responses and tons of help on any questions i have and help i need, to tuning on THE WEEKENDS from time to time and even providing information on what to do or not to do and what to look out for on any concerns i had on the vehicle. I’ve had no reliably issues or problems, proving Scott is a man of his word in “tuning for the best power gain while also for the most reliability and the safest ways”. I still daily drive this flex fuel tuned Ats-V with all the bells and whistles as far as mods and parts like if it was brand new off the Cadillac lot! Have gained an increase of power from about 400 all the way up to 630 (factually proven via dyno) all without breaking the bank! I do not regret any decision I’ve made going down this path with this company, the only regret I had was not doing it sooner than I did.
