Overrun = same trims as idle, it corrects on idle and applies on overrun. However during overrun injectors shut of anyway so its purely cosmetic. Sounds like a maf scaling issue to me. Make a log with some third gear pulls and closed loop driving and share it with datazap.me. Trims only tell part of the story. How afr compares to commanded afr tells a lot too.
