I don’t have a lot of RB motor experience but in general as you accelerate the mixture should lean out…you shouldn’t be going lean then rich then lean again. I wouldn’t personally be beating on a car running 14.xx AFR at part throttle, especially under boost. But again I’m not familiar with how RB motors are setup…given however most turbo applications don’t like to be any leaner than 12.0AFR

Thanks, I thought is was weird.
