Yes, it feels and runs really well. I have subsequently checked the speedometer vs my GPS and they agree so my tranny to ground gearing matches what GM expected. That makes most of the driver info center readings reasonable within GM's error factor (which can be large?). It does significantly aid in speed monitoring. This thing keeps wanting to float up to 70 or so which is getting a little fast for a motor home.

For the first 222.2 miles, the DIC reports 12.9 mpg. That compares to 7.0+/- for the 440 that was removed.
