DO NOT DEAL WITH THIS COMPANY or Patrick Crow. once those clowns get your money, you can forget about customer service, Yea I got burned by the dirtbags at walking-J, I have a tune that I cant use as it is down right dangerous!, the truck revs up to redline at the slightest touch of the throttle, it will leave rubber just trying to creep up a hill. he blocked my calls and emails, and even with all that proof, paypal still sided with the seller. so i denied the charges with VISA but of course it took 3 months to get the "custom tune" done. just enough time that visa could not dispute it! coincidence?? I think not. $400 down the drain and a month of lost work because the truck was down, bought a "heath tune". that MAN stands behind his products. worked with me until it was perfect and he always answers the phone and is there to help. like a good business man once told me, a happy customer will tell 100 people about how great something is, a burned bitter customer will tell 1000 or more how his experience was not good.
