Cold Advance... I was thinking you could just un-tick a box and turn it off. I guess not. Just make it all 100%. There is no reason to have advance go to zero after start.
I would try, at 70F, "15" for priming (with existing, stock injectors), and "200" for cranking.
Then, if it starts, but stalls quickly, Add ASE.
If it starts, but runs rough and then smooths out, remove 5% Priming, Cranking, and ASE.
If it does not start, keep adding cranking % until it does.

Erat, I also use a lot of priming, but more so at lower temperature. At around 70F, my priming pulse is approximately equal to cranking pulse. At 40F, it is about 2X, IIRC.
This is tripling OP's present level.

Went out this morning. Tried what I had last and ... nope. Increased the priming and cranking like you said. Bad thing is when I turn the key back it primes it again.. then again and again after every try. Which I feel makes it worse. Even tried flood clear. I didn’t let it start so I can try again in a bit. .. I also just realized that in my thermostor tables I had it set to coolant temp sensor instead of air temp sensor. I will switch it next time but how bad is that?

Keep trying setting changes. But I would start thinking about other possibilities other than MS3. You need to check your O2 sensor, IAC valve, MAP sensor, boost leaks (around the manifold) - check your brake booster path, your MAP reference path, your wastegate actuator path - NOT JUST VISUALLY. Pull your spark plugs to check for fouling, check plug gap, etc, etc, etc.

I am not sure how to check the IAC but checked the rest. Pulled plugs black and wet from fuel. Gap is 35 and they are BKR6e.
