I wish I would have ordered my ECU from here in the first place. Outstanding service with exceptional shipping. Ordered on a thursday night had it the following monday. I have a 2005 Ford Ranger 3.0 and the ECU arrived plug and play and truck fired right up, which is more then I can say about that place in New York. Do yourself a favor spend a little more for a product that works.
Didn't deliver what was agreed on, didn't communicate well with my email, definitely a trust issue here and want use this firm ever again.
Great people. Was delivered on time. Would buy from again
Being the first time I`ve had to replace a PCM module in a vehicle, which by the way , Dodge quit making it for my model vehicle. Protech was very timely with preparing and shipping the new module. When I called to verify that they would be able to handle my needs, they were able to simply explain what was needed and would need to be done on my end (which was extremely simple). % minutes after opening the hood on my truck, I was closing the hood and back on the road withoit the annoying dash lights popping on 3 minutes later
The turnaround time was just awesome, I have not even got the truck back in the shop. Iam very HAPPY thank you
Could not find an ecm for my son’s truck anywhere. Glad I came across pro tech. Right part. Quick shipping. Problem solved.
Communication was excellent. Product worked as it should. Product was delivered before expected.
2002 Dodge Durango PCM, works perfectly, shipping was very fast.
Great people, fast shipping, 2nd time dealing with protech and I will continue to do so. Have dealt with several other companies and these guys have been the best by far. Thanks for the solid products!
Chris answered the phone and answered questions with knowledge. Received my PCM in good bubble wrapping by UPS, and was installed without issue. So far so good. Pcm is in learning mode now for a 2005 f350 6.0. I did notice right off the shifting timing changed for the better. Hoping it will restore better MPG and healthy operation. Thanks Protech for what you do. A+
Anymore, Amazon sets the standard for keeping you informed about an order. I was very happy with ProTech. I had to call in my order and I immediately got a live person to help me. After getting all the information on Monday afternoon, I got my tracking info an hour later and my PCM on Saturday. Everything started working right away. All the gauges were accurate and the tranny came out of limp mode and went through all the gears. I am very happy with the service and price from ProTech!
PCM worked great. I had great feedback and was contacted by them to ensure I was aware of the process. Great service. Definitely would recommend.
We put the order in and within a days we got called to verify part numbers. Got the new board a few days later and it worked great.
Plug and play. Received order quickly. Worked great so for. Thanks guys.
