I'm surprised that you didn't take the opportunity to set the regulator to 58 PSI during your test run (when the fuel system was out of the car). That's what I plan on doing... I don't want to risk inducing detonation upon system initialization.
Glad that you're taking time to celebrate. I find it hard to kick back and rest. Congratulations--I wish I could see your reaction when you drive! Oh, and . . . beware of the alignment. You'll probably be fine in dry weather, but add some water or snow on the road, and your crazy rear toe numbers are going to make it hard to control the car.
