For all the trim pieces, just back the clips with a piece of TESA tape (cloth tape).
A common rattle is the plastic piece above the steering column and below the odometer. Just put some cloth tape on the little J clips sticking off the bottom.
The center console rattle could be from a couple...
Chatter and a cracked transmission arent good signs. The transmission needs to be dropped and inspected fir proper diagnosis.
I wouldn't keep driving it and making things worse.
I would ensure the brake caliper pins, back of pads, and the contact points for the spring clips have brake grease.
My oem pads squeaked after some normal wear. For street, you can swap to Powerstop Z23 / Z26 pads and they are low dust, and dont squeak. For more spirited driving, check out...
Some things to check. Sorry for the long list but it could be a bunch of things.
Remove rear wheels and mark axle nuts with witness marks (white paint) to ensure they aren't coming loose.
check the differential bushings aren't cracked or failing
if there was any suspension work, clock the...
These are menu options (on/off) in Forscan under the module's settings. I think you would be safer using Forscan rather than editing the values directly.
If it's under the battery, doesn't that mean it's through the firewall and behind the glove compartment? Have you dropped your glovebox to peer behind it?

You can use a Windows laptop and CyanLabs Syn3 Updater to try to fix. On the utility tab, you choose...
Mustangs don't have cylinder deactivation.
I agree with @junits15... I don't think this is necessarily the cause for your "annoying engine stuttering," based on the report you provided.
I also agree with with @ORRadtech who is encouraging you to not ignore engine stuttering as it could be a...
It is normal for the battery control module to regulate the voltage betwee 12V-14V, to prolong battery life. Rapid charging batteries kills them faster.
Always do a BCM reset after replacing your battery.
75w-90 is fine. Go with 75w-140 for track use. Add in Limited Slip additive for street use to quiet the Torsen down.
I agree that Amsoil probably already had the LSA in it.

On premium oil, I usually see 221F-225F here in Miami. If I swap to Motorcraft / Ford oil, I will see 226-231F. Ambient temperature doesn't seem to have much effect on the peak oil temperature.
