"Sept. 2006, Bought a 30019 for my 2003 off eBay and the ass hat didn't reset it back to stock. Swears up and down he did, then accused me of trying to rip him off by programming my truck and wanting my money back. Even said that the VIN in the programmer wasn't even a truck he had ever owned. Fricking kids.....The guy lives in DRTYFN's neck of the woods and I almost asked DRTY to pay the ass hat a visit but it was my screw up and just went the following route.
Sent it to manufacture (talked to a fella by the name of Kenny), paid a couple hundred dollars (in the end I paid full price, eBay cost and manufacturers cost, figured not a big deal) for a new one with the current software and learned a lesson, don't buy a programmer off eBay. They said they have had the same problem over and over with folks buying them off eBay."
I have since used the programmer many times without a problem. There are different programmers out there and to each his own but buying one second hand can be risky.
