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?

Ill try and help clear things up a little.
1. Yes you can keep the CAI and Bill can compensate for the tunes.
2. most people recommend here, including me, that you take the CAI off and put the factory intake back on, then do the "Gott's mod". search for it here and on other web sites and you will see what we are talking about.
3. return it and do either of the 2 options.

I vote number 2, then sell the CAI and use the money for the custom tunes from Bill!
Hope that helped!

Thanks Tico it does help I was thinking of putting the stock intake back and using the tuner.

Put the stock intake back on, perform the gotts/dwv mod and get the edge converted to a Gryphon with custom tunes and don't look back.....
