yeah canned level 3 and its very quik chirp i dont wot all the time and its probably nothing serious but its sounds kinda crappy wasnt sure if there was a fix for this. Whats with this gryphon program u guys are all talkin about does it just super charge your edge basically? is it worth it and whats the cost?

Hey guys I have an edge programmer and the question i have for you guys is this, If you floor it around 65-70 the truck takes off nice but when it shifts wide open throttle into 3rd there is a squeaking noise. I had this same noise on my 2005 crew cab with the 4.6 and the same on my 2006 crew cab with 5.4. I am pretty sure it is just the belt slipping as my edge is set on level 3 and my shifts are very firm. What i want to know is there a way to eliminate it?

check to see at what rpm you are shifting. the motor reaches max hp @ 4750rpm. once i found this out, i set the wot shift @ 4900 in 1-2, and 2-3. set @ 4600 for 3-4. not only did this stop the squeak, my 0-60 improved. my shift firmness is @ 15 across all gears.

I used to drive around in an E350 with the 5.4L and it would squeal the serpentine belt when shifting at WOT. My F150 4.6L hasn't had this problem yet, but I tend to let off the throttle just a tad bit to make it shift (then I get back down on the gas). If you're going to try a belt dressing, be sure to read the directions on the can first because a lot of dressings say not to be used on serpentines. I'd try one of the higher grade belts that the other guys mentioned.
