before you go buying a new carbie, go get a dyno shop to do a couple of power runs then they can actually see what the afrs are doing in real time under load.
an afr gauge is only half the battle to getting a tune right while 14.7:1 may be stoich and ideal at cruise you will be loosing power under load as best power is made at about 11-13:1 so if everything is working right you should be running rich under wot then lean off when at cruise. if your only at 14.7:1 under load then your at a much higher risk of pinging and proobly running less timing than ideal to compensate. the point being that if your down on power your going to be using full throttle or more throttle more often trying to pick up and maintain speed
