I need to double check, I am pretty sure the new car has stock setup so I can make the change once I get the car running and compare.

I know have the vent right where the exhaust is (like Jeremy and now Devon has) because it's a high pressure zone where as the back isn't so it won't make as much of a drastic difference.

One thing I forgot is that if this is on your 1G that's to cool, you need to be at least 190 for the ecu to switch between open and closed loop.
