Praise and complaint about trip to Renassaince Cycles in Tucson

I am in the military down in Sierra Vista and went up to Tucson tonight to pick up some new spark plugs as my bike had fouled the ones in it. he were super nice in staying open until I got there (10 minutes after they closed) as I had called them and told them that I was coming up but had hit traffic on I-10.

When I got there they had the plugs ready but I asked them if they had a set in heat range 8 to try. They said I should talk to Steve first (head mechanic maybe?). I told him I had fouled out a set of plugs and showed them to him. He asked a few questions about the bike and the subject came up that it was tuned recently. As soon as the words Power commander came out of my mouth he looked at me like I had the mark of the devil on my forehead and walked to the shop area. When I first went there to get my initial service done on the bike the topic of tuning came up (Zard exhaust was making the bike run lean). They said they don't believe in dyno tuning as it serves no real purpose. I sent a buddy up there that had a M600 that was running a little lean and they tried to richen it up but he said it still runs like crap. He may know more about Ducati's than I will ever dream to know but I know for a fact my bike was running lean (14.0-15.0 AFR) before the custom map and it now right around 13.2 across the powerband. For them to look down there nose at a guy because he wants his bike running the best it can is just bad business.

I don't know if this is just an isolated case but I will not use their shop any more for service. Anyone else had problems with them regarding tuning?
