Oh, yeah....
Different people seem to like greatly different tire pressures, even within the Evo X community.
I like 46psi front, 48 psi rear. Most tires I've had on my X had a little mark to tell you where the scuffing should come to on the shoulder. At 44psi in the front, the scuffing started to wear those marks off. At 46psi, it looks about right.

AlIgner should know he needs to adjust toe after camber. That's a given. Is he saying at -1.5 (or some higher camber than what he left you with) he couldn't get toe back to zero? THAT sounds a little ridiculous to me.
If he is saying he could only find the -1.1 than that makes a little more sense. Sometimes you gotta go a little nuts to get this last .1ths for camber. Loosen every bolt on the strut (top and bottom). Mash the top in and tighten. Than has someone mash the wheel negative camber forcefully while you tighten bolts

Maybe the adjustable parts on the X don't have as great an adjustment range as the previous Evos.
I'm also open to the possibility that he wasn't an expert. It was a tire shop, not a race shop. I had to hunt for a shop with a laser that would go under my air dam, and even that shop probably doesn't get sports cars or special requests very often.
I've been to more than one alignment guy that didn't think to loosen all the bolts at once. This one guy in New Mexico was so bad I thought I could do a better alignment in my driveway by eyeballing it.

Man I wish I would have read this thread before today. Just ran my first auto/x event and didn't do so great. My tires were way under pressurized and I can't believe how much I was sliding around. Understeer/oversteer Ughh. I can't complain though, I was beating the guy who invited me, so I guess that was a plus.

The Viper worked right, and still killed more cones than me! That was hilarious!
These days I drive on the street with more pressure than what the factory says, and raise it some more for race day!

Yeah for me it was a bad combination of low tire pressure and pi$$ poor driving. I really should have prepped more. What I wasn't really ready for was how quick everything happens. I worked the first group and drove the second so I wasn't able to get settled down and watch the others before I went out. By my fourth run I was starting to settle and get into a groove but it all just flies right by. The miata's and comparable cars were running 64-68 seconds and my last run was a 68 with 2 second penalty for a cone so 70. After checking out my tires though "wow" can't believe how much damage they took.

Are those cold or hot pressures?

Yes. 
Once I decided on those pressures, I started off each event with those pressures. On each run, the front tires gained 2 or 3 psi, so I was letting that pressure out between runs. The rear tires didn't gain any pressure (they have a lot less work to do).

Street tires.
Most of the time I've raced my Evo, I've been racing a stock car in STU. Stock suspension, stock exhaust, alignment within stock specifications.
I've noticed some Evo owners talking about having higher pressure in the front tires than the rear, but they're usually on STU or SP suspensions, with front camber of -3 or more.
Since I put the rear swaybar on my car, I've gotten better results with the front and rear tire pressures being almost equal. A couple of months after I installed the rear swaybar, it was legal for the Stock category.

Do any of you guys run ballast/weight in your
vehicles for events?
Im getting rid of some bilsteins and had them packaged in my trunk, long story short, my car has never handled so well around town, power distribution felt very neutral, and cornering was sharper and crisper. 70lbs of weight in rear.
Thinking about taking out rear seats and backing and seeing if it still feels just as good
