I got my chip today and all I can say is WOW! Its like a new truck. The 120 race is more than I expected,
I have a very big grin in this tune. I like all the tunes, (stock, high idle, whisper, 65tow, 80e, 120race) My only complaint is the whisper could be a little more quiet and I missed the sale by a week. I hope I can keep my foot out of it long enough to see if mpg improves .
