I'm an O/O every penny counts I started having problems 8 months ago with the Odometer 1of 4 shops told me it was my CPC the other 3 had no idea . I found ECU Pro at the truck show we talked a little he said no guarantees but they think it would be a good idea to send it in to be checked out.So months later I call and talked to Dave here I am stressed out of my mind at this point I'm broke down at a truck stop in Idaho over the holidays,Dave told me yes just send it to me and we will get on it,well I get I out and overnight it to him. Well ECU Pro are PROS I sent it to them on Tuesday and got it back on Friday I can't thank them enough Drivers all I can say is if you need help with anything that ECUPro does and you don't want BS call ECU pro . And to Dave Thanks again and have a great Christmas
