from a Shell attendant screw-up, I figured I'd log correction factors to see if it makes a big difference. This is in 46 degree temps.

6040 46.32 17.4 30.8 0 0 1.5 2.2
The worst I've seen with 93 octane looks like that last line in much warmer temps. So no Englishtown until this gas is completely used up (13 gallons left!!!). It's a mix of 5.3 gallons Shell 87 and about 9 gallons V-Power. That's roughly 90.8 octane. Also, I've never had my throttle angle so wide open before. Good to see that.

even those CFs are much better than what ive seen...i need to do a more recent log one of these days
5bar fueling 34deg F:

3bar tt180 injectors 25deg F:

I dont have a log of 3.5bar which i am running now.

probably intake temp <=> stock smic
but...the CFs did go down slightly with the new fueling.
once i finish my SAIP relocation my car will stop running pig rich for so long on startup, CEL will go away and I'll do some more logs (after plugs/oil/seafoam).
then i'll be able to see any change from the move to 3->3.5 bar.
conversely, the fact that you are running near zero CFs means that your setup is capable of more power but the software is holding it back.

...to intentionlly running lean(er)?
i probably wouldn't do that now that the weather has changed...unless you make sure to change it back in the spring 
do you have a MBC in parallel? maybe you could get more power by cutting off a boost spike if there is one? (i know you dont have a map sensor)
I guess logging N75 duty cycle might show what the ECU is doing.

it doesn't spike to the point where it can't keep up. It boosts really smooth
no MBC. I think I'm going to just leave it alone. It runs great and doesn't consume too much fuel, so I'm happy with it.
