Drove 100 miles to lean, any damage Options

(IMG:style_emoticons/default/sad.gif) Well I took my 2.7 cis teener into the shop to have a tune, they did the top valves, (bottoms to soon be done, need to drop the motor and machine the covers ect) and picked it up last week. I failed emissions prior to this something like 4% CO... Well He told me it would now Pass cause it was at 1.8 CO and after the test to bring it back to him for some more tuning. I drove it home and put it away, Seemed to run ok, and a little popping on decelration. Well That Was last week and I decided to drive down to a vw show over the weekend, I put about 120 miles total on and she popped the whole time. I am a newbie and am paranoid that I ran her too lean. I called him this morning and he said yes she was running lean and he thought I was not going to drive her until after the smog test and I brought her back for a readjustment. I said he never told me that. Car never went above 185 degrees but I did run up to redline. Could I have caused any damage. Please remember I'm a newbie, and a paranoid one at that. Ferg.

(IMG:style_emoticons/default/blink.gif) Thanks guys I needed some reassurance, cause when I called my mechanic I got the "oh I thought you were going right to get it emission tested", and "didn't I tell you I set it up lean" comments, that did not exactly put confidence into him, but he said it was not super lean and that it was no biggie. But that's coming from the guy who did not explain everything to me in the first place. Oui. I promise pic's very soon BTW. Ferg.
