I don't see anything mentioned about the fuel management. Probably had something added to boost the fuel pressure, but what about the mixture itself?

I'd suggest something on the order of fuel management, similar to a stand alone system, or at the very least, an Air/Fuel Controller, such as an A'PEXi unit. Their SAFC-II is in my car, and even with just a Cold Air Intake, I noticed the difference. Just need a dyno tune to be precise. But with all your improvements, that would seem like fun anyway!
