Thanks for the reply guys.
So since I had already purchased the intake and it would have had a restocking fee, I went ahead and installed it to give it a shot. I figure I can remove it and go back to stock or gotts down the road if I want.
Sound is great but not overpowering (which is wonderful)....if I do get on it, it does seem a bit more responsive and seems to pull slightly harder. But my initial observations on MPG seems to be worse.
I haven't had my Edge CS for long, but previous to the CAI install i could set cruise at 50 mph with AC on and on a flat road get the Edge gauge to be in the 21-24 mpg instant read range....it seems that the same setup on the same roads only is netting approximately 19-22 mpg. Now, I don't fully trust the instant read gauges on the Edge so I'll reserve full judgment until after I do hand calculations on a couple tanks, but my driving style has not changed, if anything I'm more conscious of it, but it seems like I may be getting lower values if my Edge gauges have anything to say. Through acceleration it also seems to have dipped with the similar mindset to keep rpms 1800 or below.
Also, on a hot hot day here in Orlando, FL I noticed the Intake Air Temps got up to 110F...previously the hottest I had NOTICED was only 106F (but I didn't monitor that closely before the install). But it's something to keep in mind for anyone else considering this.
If I could get the same mpg (hopefully slightly better) with a custom tune than before the CAI install then I would probably keep the CAI for my initial observations on performance and sound (might help with passing on the highways). I'll post an update later after I get through a couple tanks and do the hand calculations.
Just to note: the truck is an 2006 5.4L 4x4 supercrew and I roughly got 12.5-14 mpg before the mods with my average over the last few tanks being in the 13's and my best ever being 14.3 mpg.
