I may be doing the Dinan tune also on the 135i. The website does not mention the addition for the Dinan oil cooler for the 135i like it does for the 335i. Is this not reccomended for the 135i as well? Should I be worried getting the tune without the Dinan oil cooler upgrade. My 135i will have the factory oil cooler, as I'll be getting the Sport Package. Did anyone call Dinan and ask about that? I don't want to risk shortened engine life if I dont have the larger oil cooler.
