The targets vs what the car actually will do vary from vehicle to vehicle. It’s entirely possible that because your tech doesn’t have access to the afr target info he’s only looking at the resulting exhaust and seeing what he sees. Tuning the car should fix this and allow the vehicle to hit targets. Can’t really blame the guy in some cases he’s probably right.
