MOD-1.0 on top of Tune...
A few hundred miles after disconnect, no significant change in reported oil temp on dash compared to pre disconnect in similar weather. Stop and go traffic, 100 octane tune, I do have my fan set higher in my 100 octane tune, however. 0w-40 OEM Mobil 1
Car drives exactly the same - no significant perceived changes for this driver
Here it is: I think your special setup is focussed on top end - Me bottom end of the RPM below 3kRPM.
Your cooling is already enhanced with higher fan speed but if the pistons are kept dry, the heat stays trapped inside the engine.
There's a real debate about TT engines not being sensitive to blow-by improvements the way NA engines readily pick up on it.
Besides MAP sensor importance, the oil pressure increase benefits the HPFP timings. This can only be achieved by the hardware tensioner.
Does your setup suffer lag below 2500.RPM ??
How good is your TCU useage of gear:1-2-3-4 : long gears or short gears?
If you want to improve your heat transfer, use an engine oil with slightly higher viscosity than 0w40 is only going to spray above 2500.RPM below that heat accumulates un-removed.
In couple hundred miles your cylinders hardly had anytime to cleanup to balance your compressions.
Try MOD-2.0 to remove core heat.
So given current setup ECU decides timings are to unchanged. You can always clear faults to positively refresh ECU operations.

So from all my reading on these topics, it seems that the Oil pump solenoid mod and intercooler pump always on should go hand in hand just for longevity purposes over anything

heat removal vs. oil spray pressure...
Actual piston spray RPM is affected by... :
- oil pump solenoid
- oil viscosity
- oil temperature
- oil mileage
Perhaps I should make a visual Scale..:
RPM
1500 : 5w40+shots.... MOD-2.1
2000 : 5w40.... MOD-2
2500 : 0w40 ... MOD-1
3500 : stock dry lubed cylinders. MOD-0
Spraying pistons at normal driving RPM requires a boosted 5w40 oil viscosity. Make sure you remember that one if you are still burning oil by the quart... vaporized to PCV, not the rings.
A 0w40 spray RPM will remain higher than 2.5k RPM and oil will burn-black and engine will store extreme heat.
4000kMi oil
Lets see that oil:
4k Mi MOTUL + Mob1 (!500ml shot)
+++ also level nearly unchanged since tainted by M1 shot mix 👍👍👍
Okay I am gonna have to be satisfied with the above
I have never seen an oil that old with that appearance. Seems Motul like its mix with Mob1.
Guess that oil maybe the legendary in your dream 10k oil... I may go 6kMi based on curiosity.
++++ came home without FAN on!!!
I drove home last night, my 100A fan was not running even after parking - I could not believe it. (I have new T-stat in couple days).
I recorded more amazing idling after soldering my ESP this week - - Notice:
-- ABSOLUTELY ZERO ICK-UPS
-- Evenly Timed cycles
It runs like a bear from 900.RPM
This is becoming quite a real good car now.
Tranny oil seems to stay cooler precise and direct just the opposite of sloppy. It's super well behaved to match throttle. I had it DROP TWO GEARS at once super easily - - Yep first time for me !!
It seems like tranny now has new ways of shifting... not a dumb box at all. TCU shares strategies with ECU.
I bet proper shifts are going to be beneficial against clutch-sludge.
