Ah hell this is just easier...

ALWAYS USE THE IMRC.
NEVER TAKE IT OUT.
YOU CAN NEVER MAKE ANY PERFORMANCE WITH IT MISSING!



Apparantly then, I don't have any clue about what an IMRC is. It is my understanding it opens up the secondary runners on the split port manifold at or around 3500 RPM.

If my understanding is incorrect, I am sorry. But being that I'm talking about a car that doesn't have a split port manifold Duratec 3L, like a Ford Escape or a Mazda 6, I wouldn't think that I would have a PCM [that] IS PROGRAMMED for them to be active, installed, and used properly. Am I wrong? I'm not talking about a Contour PCM.
