New MAP Turbosmart WGA installed and retuned with Cobb AP TEPHRA MODS!!! It's nice having knock CEL and 93/91 map-switching back :)
Ported exhaust manifold: 411/367 @ 26psig
Short-runner exhaust manifold: 416/374 @ 26psig
Gains are gains, I'll take them! I think this really proves that my stock cams are pretty much maxed out and the bottleneck in my system at this point. Chart coming soon.

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 :D

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.
