Two Questions.

I have an 04 f250, and i just put in an EGR delete. I want to upgrade my oil cooler, what is the Best one to get. I tow...alot, but occasionally i run it down the track. Also, what strategy should I run, VXAP1n3 or TQATONB?

ok first off the factory oil cooler is fine. they redesigned it for larger coolant flow. i run that and tow alot and basically do everything that you do and mine is perfect! now for the strategy the vx---- is the pcm tune the TQ---- is for the tranny

Yup, the oil cooler is not the issue, it is the coolant and the build up in the system.
I would do a coolant flush and put some EC1 or ELC rated coolant. Along with a coolant filter. I have the Diesel Site coolant filter system.
Napa auto parts has "ZEREX Extended Life heavy duty formula Diesel Ready" EC-1 rated coolant that I bought for my truck. It is ~$17 per gallon. Only get the concentrated coolant, what ever it may be.
