After receiving my Fuelmaxx in the mail, the instructions were simple to understand and follow. I installed the chip and proceeded to drive the 150 miles that it stated. During that time I did notice the device blinking once every 4 seconds but never had any change in power, torque or fuel mileage. I contacted the seller and explained what was happening. He stated that it was trying to reflash the pcm and to follow additional steps. I followed the steps that the seller sent to me and again drove over the 150 miles that was requested. I still had no change in hp, torque or fuel mileage. I spoke to the seller about the issue and we determined I would continue to drive with the program to see if there was any additional fuel mileage gains. I put an additional 500+miles on my truck and did not see any change. The seller had done a great job in trying to fix my issue.
I am not saying this product does not work. It just did not work on my 1999 Super Duty.
The seller was awesome and very proffesional.
Thank you

Perfect fit.
Item as expected. When you buy OEM, it is always better than aftermarket.

Good lights
Small but powerful light. The flood light gives a broad light pattern. They give a bright white light. Easy to install.
