I have a 2005 FX4 F-150 with an edge evolution programmer, I want to run an intake, but I've heard the horror stories about engines shutting down and going into "safe modes". What intake can you run, (if any) and what steps do you go through to get it back if your truck does this?

 

do you have a 3 valve motor (5.4)? or do you have a 2 valve (4.6)???

 

I have a K&N cold air intake on my truck with the edge and slp exhaust its all been on there for 30k now with no problems at all. Mine has the 5.4L 3 valve

"We can tune for different cold air intakes on 05+ Mustangs and 04+ F150s. Any aftermarket intake that flows well and puts the slot-style MAF sensor into a larger less restrictive housing is going to REQUIRE a tune for the vehicle to run properly. Intakes that do not require a tune are often just as restrictive as stock and do not result in large power gains." - Justin Starkey, VMP Tuning

"I'm not necessarily saying that a CAI is bad for the engine, but my concern is the fact that the AFR is already starting out at a dead 14.6 to 1 and historically CAIs cause the engine to run even leaner. I certainly wouldn't be running a CAI without appropriate tuning to correct any resultant lean problems, especially when I can pick up 7+ HP with a simple, free modification." - Bill Cohron, PHP

FYI - CEL's are not always triggered even though a solid lean condition is present. Fact is - you can't tell just by looking. Or hoping it ain't gonna happen to you....

 

MY truck was dyno tested at to places to check for running lean conditions and was not running lean.

 

mine runs fine with no lean issues
