whats the optimum air fuel ratio during WOT for mk4 gti (AGU)
I always thought the "optimum" AFR was across the board, not just WOT.
That said is around 12.1/12.2 in a general sense but as your probably aware can differ per type of car.
Sorry I'm not more help but safety wise, richer is better than leaner in a turbo car.
