CAI with edge
I have an edge cs on a 2007 screw and was wondering what i can do if i get a banks ram air intake. i know that the 5.4 will run lean without a custom tune so is there a way to adjust that with my edge? Ive tried searching for a similar thread and had no luck. Any info would be greatly appreciated.

Anyone retailer who states that by merely installing an aftermarket intake will create a lean engine condition is , well......how do I say this.....the PCM and sensors are all designed to track and ensure the fuel mixture is correct and if it's not, it will adjust the fuel mixture up to 10% to compensate....you would have to have a lot of engine performance mods to exceed that or have a real special circumstance of elevation that would create an excessive lean or rich mixture in which case, the oem has e-based solutions for.

The 5.4 flat panel oem filter will flow up to 500 cfm, the cone filter will flow up to 1000 cfm (because of more surface area), the 5.4 engine has a max CFM intake of 480 (sorry but the laws of physics at work here)....if there is any minor adjustment, the pcm will more than take care of it within 50 miles (or more likely immediately after warm-up)

And the throttle body ultimately has the final say as to how much air enters the engine.

You are missing a key piece of the puzzle. The problem is not the cfm of the filter. It is the relocation of the MAF on some CAI kits that causes the problem. On the new 3v engine the MAF relies on the location and volume of the intake after the filter for its transfer function. Before 04 on the 2v engines the MAF had its own calibrated volume and was not upset by relocation in CAI kits. The lean condition is well documented in 04 and early 05 motors even with stock intakes. Ford did make some changes after that.
