Ever done a coolant change? I think the aggressive/race map makes the pump run harder too.
mine is a 08'....FEB 08 build date....and i do have stock oil cooler.
coolant change was done less than a 1k miles ago when the water pump failed the first time. i'm hoping i just got a bad pump...otherwise i have no idea what the issue is. i was at the track end of Oct running the Cobb Race map...and the car ran flawlessly. for daily driving i run the Stg 2+ FMIC Agressive. at the time of the first failure....i was running a Procede.
