I just had my 70,000 mile servicing (at 65,000) miles. I've had my mp215 kit in since about 6,500 miles and I seem to recall that it is recommended that the plugs be changed every 10,000 miles with that tune. I did that (for only the second time. I've been going about 20,000 on a set of plugs) but also had the air filter replaced (with another mountune unit). As long as it was going in for servicing, I had them install my set of Bilstein B8s that I've had for a few months.
I have noticed an immediate improvement in the fuel economy (It's been degrading slowly over the years) and the car seems more peppy. It's easy to forget how good these cars are when they age and the little things that should be done accumulate. I've taken it to the dealer for service every 6 months since new, but this last one gave me back all the zing for which I originally purchased the car (AND the tune).
Just a reminder to all... replace those plugs and filters.
YMMV
My 2¢
Oh, I know there are many who won't let a dealer touch their cars and/or would rather do their own maintenance. Been there, done that, I'm old, and hate working on cars but love to drive.
