Im not sure what the reflash changed to be honest. Searched around before I had it done and everyone seemed to get the same results I did.
Piston noise before warmed up..?

i think that TSB is '11 specific as well, mine is a '12.

There is a tsb to flash the ecu with an update. The noise is the cam phasers. They are very high up and it takes a little while for the oil to get up there to quiet them down. There is no fix for this. It's normal. I have driven 3 5.0s that have done this since new.
what does the ECU flash do?(besides flash it lol)
I hear some cold start engine noises. They go away after the car has run for a little while. I also have one of the ticks. Whatever, it runs like a beast...albeit a noisy beast. I also, apparently, have bent axle flanges. So much fun!

Mike what is bent? The acutal shafts or the tubes off the housing?
I had the engine tick after the oil change way back at 3k, took it to the dealer got the run around, blah blah....well a buddy of mine told me to switch over to penzoil Ultra 5w30 cause it cured his tick....well sure as heck as soon as i switched over, tick was gone. Its been almost 5k tickless....idk what it is about PU but it worked
I was running german castrol, redline, and pennzoil platinum
Interesting, I'm waiting on Ford to call me this morning. I'm sure they are going to tell me what the tech looked up which is the note the boss mustang does this as well due to the aluminum forged pistons. I'll keep yall posted on what they tell me.
The flanges..the flat portion at the end of the axle. Apparently Shaun also had this problem. It is evidenced by low speed squeaking from the rear and squeaking under braking.
Mike
Just can't contain all that awesome!
LOL, I guess! Apparently this is a defect, not an issue caused by hard use or launches. I am thinking of just upgrading the axles when I do gears.
Mike
Have you checked the runout on them or just assumed that was the issue? How did you guys determine this was a defect?
I'm going to ask my Mech at Ford today how much he will charge to put gears in mine
Shaun checked his. I am going from his experience, as I have the exact same sounds and issues with mine.
When I do gears, they will likely be 3.73s.

this^
Just got back from Ford. They told me that they really couldn't replicate the noise but they are going to do the stretchy belt/timing cover TSB on the car. I should get the car back tomorrow afternoon or friday morning.

I have no idea. But I could swear that the noise was less, and the car was more powerful. It changed my strategy code though. Since then, I pretty much forgot about that cold start noise, and I let the car warm up a long time.
well picked up the car from ford after having the stretchy belt replaced with the new timing cover/tensioner setup. drove the car home and the CEL comes on and its the P0024 exhaust cam shaft timing over advanced. so back to Ford she went, hopefully ill know more tomorrow.
Hey guys this may sound weird but I had this same noise and I just recently swapped to a lethal h pipe and a gt500 Pcv valve both at the same time and have not heard the noise since. I have a feeling it has something to do with the Pcv valve being more restrictave and not allowing so much oil to push through the intake.
