HELP WITH HP POWER ISSUE over 15psi
I think bigger picture it was more of inability to control a few of the injectors because he stated that the pintles were stuck, or something like that. So AFR is more of an averaged measurement of a single bank of cylinders or even all of the cylinders, but since it was a bad couple cylinders, it didn't show up as an AFR issue.
Think of it this way... if you have one injector that's dead, you can compensate the afr by increasing the rate to the other cylinders since it's just an averaged value. But in the end, you're going to be down on power from both a dead cylinder, and running over rich on the others to make up for the afr error from the dead cylinder. It's why a lot of the high HP guys go to individual egt sensors at each exhaust port so they can see what's happening at each individual cylinder.
