Thinking about a basic tune but ... 85K on the clock. 95+% highway miles, always driven for fuel economy, full synthetic oil always changed with 20% remaining on oil life monitor. Miles not an issue or should I just forget about it?

If you got the cruze for MPG's and drive as such. A tune may decrease your MPG's. Many, including myself, have reported that a tune wakes the car up and thus is more fun to drive. I detuned our car after one update I didn't like and the next morning my wife said "WTF did you do the to car!?! It's feels like a paperweight!!! Change it back NOWWWW!!!" So I changed it back. If your looking for some type of performance kick, a tune is the answer.

I wouldn't be concerned strictly because of miles. If you've taken proper care of the engine (which it sounds like you have) it shouldn't be any weaker now than it was new. I've never given a second thought to tuning mine after the powertrain warranty expires.

Go for it. Your engine is fine. I know a couple of guys who are tuning original unopened blocks on Buick Grand Nationals and T-Types. Upgrading from stock turbo. Some are at 110k miles. They are just fine, because they are taken care of their cars.

If this were a Subaru forum we would be telling you that you are near the end of the turbo life and possibly in the engine rebuild state.

You should be fine but upgrate to good oil for engine and trans. Plenty of threads on what oil is ok for what conditions.

Toyotiac Tune it and you'll never look back except to ask yourself why you didn't do it sooner. : )

I have a 2012 ECO MT. Bought it used with 73k miles. I knew about the tuning before I bought it, but hemmed and hawed about getting it for a year.. Almost rage quit the car many times for its sluggish nature. ESP on low power, hot weather days. NOTE, I test drove it in moderate weather, didn't realize the power hit it would take in the summer...

I did Trifecta Advantage tune around 88k miles. I'm at 96k now. Its a different car, enough so I don't even car about the MPG. Before, I justified the little slug, comforting myself that it got 40mpg. Trifecta did an update that I got a few weeks ago and its even better. I REALLY like the Trifecta being able to switch drive modes, and that its octane adaptable. LOL, not that I ever run anything but 93 in it now. I tried a tank of 87, yep it works, but 93 has more pep so like the MPG, I don't care and run 93 always.

With the basic, for stock, Trifecta I'm seeing 42mpg in stock/eco mode and 35mpg in sport/touring mode. and yes, I drive it harder in sport mode, which is mostly the mode I run in.

To be honest, I still don't love the car, but with the tune I can live with it and be reasonable for a while longer.

Hope this info is helpful if not a little amusing as well.
