265 is going to be a bit pinched on an 8.5" wheel. This will provide a more vague feel as the tire flexes laterally more than a narrower tire would. The actual performance implications of that are debatable, but it's worth keeping in mind.

Car has 10k fronts and 11k rears. Whats the main reason running 255's over 265's, fitment? In my head I have the mindset of 265 is more contact patch than the 255's which means it should be better overall? But will there be a negative impact if it bugles out a tad bit that would make the 255's a better choice?

Merely increasing the width of a tire doesn't increase the area touching the pavement. It just makes it a wider, shorter patch.
+1 for 255s on 8.5" wheels.

I appreciate the input from everyone, I believe I'll get the 255's. Obviously re-71's would be the quickest but I'm worried about the quick wear from it since I daily and autocross. I would like to get 10-12 months from daily driving/autocross mix. I do about 12-15 autcorss events a year. Would the 71's last that long? I'm kinda eyeing the Hankook R-s4's since they seem to be almost as good but having a lot better wear.

If you're running a "normal" STU alignment make sure you rotate often; I try to rotate between every event. If you're 0-toe and you rotate you should be good IMHO but if you drive a ton of miles maybe not.

No mention of the Open ECU proposal since last month, has this proposal been recommended to the BOD or is it still out for comment? Trying to figure out if/when I need to get the car re-tuned

You can raise the boost via tuning on an 8/9, but the stock boost pills (that can't be removed in STU) limit you enough to where you may not see much/any gains. The X definitely has more power to gain in this scenario. Either way, I have an 02 eliminator downpipe and new intake to install so I was going to have to retune anyhow :P

Yep.
"Non-standard brake rotors may be used provided they are of equal or
larger dimensions (diameter and thickness) and made of ferrous material
(e.g., iron). Thickness includes the individual plates of a vented rotor,
as well as the overall dimension. The diameter for replacement rotors is
measured at the minimum outside dimension. Aluminum rotor hats are
allowed. Cars originally equipped with solid (non-vented) rotors may utilize
vented rotors. Cross-drilled and/or slotted brake rotors may be fitted
provided all such voids are within the disc area and comprise no more
than 10% of that area. Brake calipers and mounting brackets may be replaced
provided they bolt to the standard locations and the number of pistons
is equal to or greater than standard. A functioning emergency brake
of the same type, operation, and actuation as OE must be present. Drum
brakes may be replaced with disc brakes of a diameter equal to or greater
than the inside diameter of the standard drum. Such conversions must
be bolted, not welded, to the axle/trailing arm/upright and must include
an integral, redundant emergency brake. Changes to backing plates/dust
shields/brake lines to accommodate these changes are permitted but may
serve no other purpose."
