To me it sounds like the tach is about half of what it should be. Like my car idles at around 850 and shifts (under hard acceleration) at about 5200 or so. So if you double the numbers you have up there, there about right. I do have the 3100, so the numbers might not be exactly the same but you get the general idea . It could be the crank sensor or some kind of problem in the wiring from the sensor to the ecm to the guage. Just my thoughts.
