I did change the plugs (dealer did) a little less than 15k ago. I have another set that I will swap probably before the next dyno run just to be sure.

The plan would be to consecutively run baseline, upgraded OEM software then a tune on the same day. Just will need the files load them between runs. Not sure if that wouldn't be enough time to allow the engine to adapt, just would be nice to do iit that way to isolate as many variables as possible.
