Thanks Ryan.

However, fuel pressure was actually lowered from stock. It does not burn oil, as the valve stem seals have been replaced a 600 KMs ago, and the rings are good (good compression) Unless it's the turbo...

My PCV system is good, I got a new OEM PCV valve. And the 255 is run using an AFPR.

As for cat, I know it's there (not punched out) however it's a 3" cat. Not sure on condition or age.
