Thanks for the response. I learned something quite interesting about my '93
GTS injection system this past weekend and I am inclined to agree with your
statement. If I set the CO to 2.0 ~ 2.5 at idle and then increase the RPMs
to 3K ~ 3.5K the CO drops to 0 ~ .5, which is much too lean.

Personally I think 2.0 ~ 2.2% CO is still too lean. Watch your HC and see
what it does, if the HC drops as you raise the CO, you are too lean. Some
people do adjust for minimum HC and take what they get for CO. Obviously
several schools of thought on CO/HC, and we wont even get into CO2 and O2. I
think 4% is a better number for all around throttle response, fuel mileage
and fast warm ups.
