Stock gauges faceplate upgrade to more RPM and MPH questions??

You could get someone like Redline gauge works to redo the circuit board calibration but it ain't gonna be cheap. I think your cheapest option would be to use a Dakota Digital interface to play with the calibration. Those years use a DRAC I think so you could also go this route:

But honestly, it would be faster to play with the DD interface. With the new gauge overlay and the cost of the module, you'd only be around $250 into everything.

Thanks .. I think you beat me to it. I just discoverd those the other day . I will have to give DD a call to see if that would work for me.. Seems like it would be possible from the description. I was also informed that I could use HP tuners to calibrate them as well. Not sure on that one as of yet. This would be a nice way to get what I am looking for and still retain that stock look..
