No.. didn't gut them at all.. The IMRC box isn't opening right so What I ended up doing was tieing them open. When I was running the 2.5 I never had a problem.. a little low end lag.. but that was it, so when we built this engine I just tied them open. With it closed the car still flashs with a missfire (Was fine earlier today after a longer run the missfire came back).. just runs a little smoother at lower RPM's. the missfire is still caused by a lean condition as the plugs are starting to glaze a little now.
