The part was correct, programming correct, and I'm now all up running smoothly again. I will certainly go to Protech Auto Sytems again should I ever need another part. Excellent service and customer support. 5 STARS!

Having never ordered a part like this online before, I was a bit skeptical at first. However, Protech quickly delivered the computer as promised, and saved me 400$ that I would have had to pay at the Ford dealer. Thanks Guys, I would recommend you to anyone!

I have been looking for months for a PCM for my truck and no luck. Finally I found protechauto, they have the best customer service and had my PCM I needed, it was fast and easy all I had to do was plug it in and go, I will always do business with protech.
