Well, I bit the bullet.

2004 Rock with 55,000 miles. I pulled the injectors and had them cleaned and flow matched. The originals were in better shape than I thought they would be. Then added the XIED. I have run a tank of fuel through it and there is no doubt it runs smoother and takes throttle in a more refined manner. I did not reset the motornic so I think it is still teaching it self. I live at 6800 ft. and I think the cold start has it running rich so my moring commute has used more fuel that before the upgrade. We have been having cool mornings lately and my ride is 7 miles so it's not getting up to operating temp. This week I have a trip and I expect the milage to be close to the old lean running herly jerky of pre upgrade. I left the XIED at the factory setting. After this trip I may adjust for a leaner setting. We will see if the motronic can figure out the altitude and make toe propper adjustments.
