Funny how this oil cooler vs aux rad arguement still comes up from time to time.......ironically both are doing the same thing (ie adding additional cooling to the engine but the effects are subtly different). Long story short, best way to eliminate it is to address turbo airflow (LBZ mouthpiece), block your EGR (prevents loss of boost pressure), larger trans cooler (removes more of the heat load), larger aux cooler (adding additional cooling capacity is key to the overall fix) and tuning with EFI (again helps with EGTs under load).
