and it actually not being there. It is nearly impossible to find even when it is there. I'm curious if it is speculation on his part based off of your results, or if it is genuinely removed? Do you know if it is there? I can't stress how important it is to test your car while it is HOT. Push the car for an hour and then get it tested. DO NOT let the car sit, test immediately after arriving at the shop. If he isn't ready for you, take it around the block and keep the motor/cats toasty as possible. Do some searching for retarding your ignition timing slightly, it will help get the car passed.
