That’s honestly very strange. I’ve owned nothing but manual vehicles in my 18 years of driving, and did not notice any of these things with the Fiesta. I did notice the rev hang when you let off in any gear, but it had zero effect on my driving habits.
Are you saying that when you push in the clutch in any gear, the revs fall very very slow? Can you post a video of this?
I will try to record some videos this week but it takes over 2 seconds to rev match from 1st to 2nd gear at high RPMs. Having owned a Miata, a Genesis Coupe, an Exige, and a WRX, and none of them had this issue. The very heavy flywheel causes the revs to fall at an appallingly slow rate. This combined with the momentary 'rev hang' when getting off the gas is a recipe for disaster in the FiST. It make spirited driving extremely disappointing and actually detrimental to the clutch as it is forced to pick up the slack.
FWIW- I bought Mountune FB1 pack and chose to disable shift assist on the customization screen. I installed my stage 1 93 octane map and see absolutely zero improvement in rev hang. Is there a separate option in the ap3 I'm missing? Just letting you know I've experienced no improvement over stock with tune.

This is exactly what I was looking for as far as feeback. The issue you're noticing is the flywheel. A tune can remove the shift assist that holds the revs on upshifts and it can probably tune out the momentary pause after letting out the gas where the drive by wire system leaves the throttle open to burn out the rest of the fuel in the cylinders for emissions purposes. But a tune can't make the revs fall physically faster when it's a flywheel issue.
You get used to it. I've owned 5 manuals over 10 years prior to the ST and this is the most unnatural feeling one due to what feels to be electronically controlled rev hangs and delayed falling engine speeds during upshifts. Made it very difficult to drive smoothly at first unless literally holding in the clutch for 2 seconds while drop occurred. Still my biggest quibble with the car but again, you get used to it. And during all my hours of surfing this forum, I have not seen a definitive solution by anyone!

Completely agree. Mechanically this is the worst manual car I've ever driven for these specific issues. It's just really unsatisfying when you try to do a really fun pull from 1st through 4th and you have 2.5 second gaps between shifts while you wait for the revs to fall. It's a massive buzzkill when driving spiritedly and it can't be overstated.
Agreed, I like to go 4th gear to 6th gear when merging on the highway and the rpms do not want to fall as fast as I want to shift to 6th.
I wish I had the v500 maps instead of the v504 just for this to be switch off.
A tune will probably not fix the issue that's bothering you. I'm leaning very heavily towards flywheel still as the main culprit of delayed shifting and slow revs falling.
Yeah only time I've ever noticed an issue with the rev hang is when skipping gears. Other than that I'd say the driving experience is pretty normal. Sure, it doesn't act like my Miata with a real throttle cable but it's nowhere near an annoying driving experience.
I don't want to rain on your parade because if you enjoy your car that's great but coming from an NC Miata it's worlds different. Either my 2017 flywheel is different than yours, you don't drive your car like a bat out of hell, or you just don't remember your miata's shifting experience because it was too long ago possibly? It's more than annoying - I don't even want to drive the car anymore. In fact it's up for sale right now and I'll probably take a $4000-$6000 loss - if I can even find a buyer.
Seriously? I can't stand the 'rev hang' either but there is no way it's any kind of impediment to driving/shifting. I've never ever felt the need to wait for revs to drop to upshift.

Don't wanna knock your driving experience here buddy but in any normal manual car if you up-shift too quickly the clutch will be used to pull down the revs from lets say 3rd to 4th. "Quickly" is 100% defined by how fast the revs fall. Ideally, when you up shift, the time it takes you to move the stick from one gear to the next is exactly how long it takes the revs to fall to rev-match into the next gear. This is not the case in the Fiesta in ANY gear. There's no single gear change in this car that you can do in a timely manner. You're always waiting for the revs to fall. 1st -> 2nd. 2nd -> 3rd. 3rd -> 4th. You always shift the stick faster than the revs can fall. That means you're always waiting for the car's revs to catch up. This is just poor design on Ford's part. And every time you wanna drive fast you have to burn out your clutch or lose momentum waiting for the revs to fall. Anyone who thinks this isn't a huge issue either doesn't have the issue, doesn't understand the issue, or doesn't know what the issue is. I'm not crazy and I'm willing to sell the car at a huge loss because it's so bad.
