Sounds like this mechanic messed up more with your install than I did with my own install! I actually just had my second bad experience with a dealership messing up a warranty repair (not properly re-assembled AND additional damage caused during the initial "repair"), and your story is not helping me regain trust in professional mechanics. I wish I had a nice garage with plenty of space to work, fully stocked with tools, and a lot more experience to be more confident in tackling any job on my vehicles.

What's the reasoning for running an older tune? Why is it running only "ok" rather than "great"? Any indication of whether they got any new info from your vehicle to contribute to improving the tune?

I bet you can't wait till Friday!
