first let me start off by saying that matt is a stand up guy who is all about customer service. he stayed afetr the show was over to put custom files on my tuner that i won in a raffel. apparently the latest flash from ford isnt compatable with the canned SCT tunes so matt gave me 3 of his tunes at no extra charge. all i can say is WOW. this is a whole new truck
. huge props to this guy. the power is unbelievable and it feels much smoother. as far as MPG gained im not sure due to it only being one day, ill keep updated. anyway if you are looking for custom tunes matt and gearhead are a great choice.
