I just recently purchased a 2008 F150 with the5.4 v8.My question is this it has a Airaid CAI on it and Flowmaster exhaust and no CEL. does the # U7151 have canned tunes for this intake like my programmer for my 06 stang does???? I believe possibly the dealer installed the intake and exhaust but I am worried it might be on the lean side.But like I said it has not given me any problems...Thanks

The u7151 tuner does not have CAI tunes on it. The F150's computer system is not as finicky as the 05-09 mustangs. If you don't have any CEL's you should be fine. But if you have access to a wideband o2 sensor you can check your air/fuel ratio to make sure you are in the safe zone.
