I just did one and using (filtering) the info from this thread I had no problems and a great outcome. As can be suspected from the comments of more experienced folks, this is much simpler than I perhaps made it sound in the beginning. Basically you just tell the tune that it's not equipped and then block a few DTCs. Mileage and power both improved considerably, especially overall economy. (No more 8-17 mog variation haha). Thanks for everything!
