When tuning on a dyno (dynojet w/o load cell) should I tune the car a bit leaner or a bit rich to have the correct AFR?
Thank you

Usually a car tuned on a dyno that can't load it will go lean on the track.
Do some third gear pulls to redline, log & check the tune. IMO street tuning > dyno. MAF tunes generally richen up in higher gears with more load. When I tune in third, automatic safety factor of 1-2 points richer lambda in 4th. YMMV.
