Hi all I am new to this forum. Have been looking around and it looks really nice. I have an 06 F-150 5.4 liter 4WD. I have been researching the Edge Products Evolution for some time now. One of my friends with the exact same truck bought one and increased his gas mileage quite a bit, so I finally bought mine. I received it yesterday and on page 5 of the manual it states that if you have an aftermarket cold air intake using the evolution is not recommended because it could cause the engine to run lean. I called edge and they are great. The rep said that I can return it up to 60 days and get a refund. His suggestion was to install the unit and if the check engine light goes on that would indicate it would not work. He also suggested that I contact Bill at PHP because he may have a custom program I could buy. I could put the factory intake back on. Can anyone help?
