I had read that as well, and was looking to do something like the attached link, but was wondering what it would look like in the standard reflector housing. Just curious at this point. Not sure I'm even going to do it.

Just had the odometer service update done on my truck, and it seems as if my truck is having to relearn its tolerances between V4 & V8 mode. Has anyone else had this experience?
