Thanks for the suggestions. I wasn't sure if tuning controlled it or not, but it looks like my question was answered.
I plan on keeping the stock fan setup, and not going electric. I do tow extremely heavy from time to time. And towing loads like I tow up long mountain passes really builds up a lot of heat, especially in the summer. That fan will kick on big time when I'm fully loaded, and I just like the reliability of the stock fan setup.
But thanks again everyone for the input. I appreciate it.
