Default Right turns car runs rich

Long story short, car has been running perfectly fine. I parked, went to class, then got back out on the road. Every right turn i made the car would run super rich on my UGEO. Left turns and straights are fine. What the hell is going on?

i'd guess the sudden drop of rpm/air flow without the necessary time for the fuel map to drop down to the next cell causes it and the difference on the left versus right is that a right is more sharp than a left...

Maybe the fuel pump is affected by fuel slopping around in righthand cornering.

Fuel pickup is on the left side. People have leaned out on left-hand sweepers. Maybe you're having the opposite problem? Do you have a good FPR? That might help.
