I had fordchip reflash my computer for my 4.10's. I talked to one of the guys about wanting firmer shifts and different shift tables so I had to get a stage two chip. I got the chip but then I found out my service port was disabled. Fordchip asked me to ship the whole computer to them and they would solder in some jumpers to activate the port and they would have it back to me in a week. Well, after checking with them for two weeks and getting the run around about when to get my computer back, I got someone on the phone who said they would just go ahead and reflash the computer for me instead. One and a half weeks after that, I finally had my computer back. But, I can say that the car shifted awesome even though I was without my daily driver for almost a month.
