For sure if you run sensors on primary tubes particularly on something dual plane, you are going to get readings all over the map. Doing the primaries is going to give you ideas about how bad the fuel distribution is but not really the best choice for overall jetting decisions. The collector is the best compromise and where most people run them. Make sure you locate them far enough upstream to not get readings from the open exhaust reversion.
