I have a 06 5.4 and also have installed the edge. I am looking at buying an intake but seem to remember reading about the drone you can get while towing, especially with programmer. So does anybody have advice, past experiences with any of this. I tow alot and can not have a ridiculous amount of drone in the cab. Also I have a flowmaster 50 series exhaust. it has very minimal drone at 1800 rpms but nothing terrible.

 

my K&N 77 whisles at about 2,200 RPM nothing less nothing more and thats the only time it makes noise. i dont know about what it'll do with a programmer.
