These are the best suggestions. It's hard to find a good, reliable mechanic or tuner anywhere that will do the job to your specifications. Quality mechanics are rare and they are good to find.

Have you looked at online review sites? Aside from this one, of course

I never thought about elevation when I thought about tuning! I guess I've lived on flat ground for so long I don't know how much different cars can act in the mountains!

Couple places to check for pretty much anything you need depending on where you live, Import Connections (Highlands Ranch) and Turbo Garage (Loveland I bleieve). Interested to see what works for you, I'm planning on getting a tune soon myself.

Old post, but I had my 1994 Del Sol with a B18C1 chipped, and Tuned by Miles. Found him surfing Craigslist. He's just outside Denver in Thornton. The man knows his way around an ECU. I've been trying to fix a problem with a fuel/electronic issue at warmup. When Miles removed the ECU he found the issue, and corrected a couple others. He checked all the components of my engine swap, and made some adjustments. The Sol runs as I expected it to now, and we will work together on some additional mods. You can find him on Craigslist, great, knowledgeable guy.
