I'm installing a new AFM now and believe that I'll then need to have the CO measured at a shop to have the mixture screw adjusted properly on the top of the AFM. Apparently, the new AFMs are delivered from Bosch without a plug at the top of the meter where the mixture screw is located for this reason. If this is true, should I reinstall the stock chips before having the mixture set, or leave the Guru chips in there? Thanks.

You will need to use a 2 gas analyzer for idle. If you run outside stock. Dyno time with a wideband O2 sensor. More than likely, it has already been set for stock use.
