Got my warp tunes from Ray last week, and like a kid in the candy shop could not wait to get them installed.
I ran into problems, (operator error). So sent email to Double R it was after hours. Got to thinking its got to be me went back out and this time succeeded. Naturally had to go for a ride and all I can say is what a difference, the response of truck is fantastic!
Have to add walked in house wife said I was worried about you. I was smiling ear to ear, guess my ride was too long. So got home and sent email to disregard the earlier email. To my surprise, at 7:00 am I got an Email from them saying great.
Double R you have my respect for a great product and awesome customer service. Thanks and God Bless
PS: Now I'M wishing I had ordered whistle tune as well.
