The P0300 is still a problem. It happens once every 10 times I cold start the car. I never get it except then.
I felt a modest gain when I installed my ported TB, similar to when I installed my M370 or when I installed pulleys. I suspect about a 5whp but I have no proof and I haven't done a retune.
