Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

I was the red GTP next to you at the meet for most of the morning. You got a bad ass setup there.

Kickass car! I do have one question though. On the valve cover breather, isn't that taking in "unmetered" air? I only noticed because I'm going through it on my Gen V swap.

Since it's pressurized air before the throttle body, you can't run a simple pcv system that's metered.
 
I do have a pcv setup for the rear valve cover. The manifold is tapped and there is a thread in pcv valve. Can't do that for the front one though. Have to run the breather for now. Until I setup a catch can breather setup.
 


Went to dyno the car and had all sorts of problems. Found the PCV was blowing oil into the intake when the car was under boost causing the plugs to foul. Found a vacuum leak at the fuel pressure regulator. Car was misfiring due to the plugs fouled. Ended up taking it home with no dyno.
Still working out all the bugs. Beginning to think this car is cursed.

I got some if the bugs worked out with the tune. Found a vacuum leak at the fuel pressure regulator. Still trying to get a decent street tune. Found out the plugs were fouling due to the pcv system blowing oil into the manifold under boost.
