I have been holding off on the tune to this point -- I did the plugs and coils at ~50k due to some occasional drivetrain malfunctions / misfires. Since plugs and coils are part of the 60k service anyways, I felt it was an easy place to start the troubleshooting and there have been no issues since. I did go to step colder plugs (NGK 97506) along with replacing the coils in anticipation of eventually doing the tune, but have continued to hold off on it. It's been about a year since putting those in and there have been no adverse affects of going to these plugs and staying stock.
