Before and after (MAP short-runner exhaust manifold & MAP Turbosmart WGA):

There is a noticable increase in the mid-range, that's where I'm really feeling it. Plus, the turbo seems much more responsive with this new WGA which makes sense since the WG was able to be properly tensioned, I wasn't able to run any pre-tension with the original 25psi WGA. Although spool does appear a touch slower, torque picks up a little bit quicker.

Knock CEL is setup at 3 counts (slow) and 5 counts (fast), but I've yet to see a single flash even with two pulls to 140+ so far 

I was just out ripping around some more and this car is seriously the ultimate DD street car! Handling is spot on, it rips through the gears, reliability has been decent, and it drives smooth as stock.

Update: ~45k miles, stock internals and stock clutch! I just returned yesterday from a 2,532 mile trip to northern Minnesota and back It didn't burn a drop of oil and ran flawlessly the entire time; even sitting in stop & go traffic in Oklahoma in 110F air temps and blazing sun. The A/C kept pumping ice cold and the idle was rock solid the entire time.

Dyno chart from the retune in June with the MAP short-runner exhaust manifold and Turbosmart WGA:

MAP ported/SPC coated stock exhaust manifold has been installed! Back to a stock-appearing setup 

I also added 20 sq/ft of GTMat sound deadening to the car and it's made a very noticeable difference.

I've installed 20 sq/ft of it and I think I'm done as far as sound deadening is concerned. It's made a nice improvement and I'm satisfied with how my car sounds.

I am very happy with the Sumitomos, they're nice street tires that have pretty good treadlife. I used them on my IX too. I haven't autocrossed my X, but I did my IX and they were also fine for casual autocross use. I'm thinking I should be able to get 30k miles out of them.
