I am the proud new owner of a 2006 TBSS. I purchased the truck with some mod.'s already on it. K and N filter, fast 102 intake, it has a tune but am no sure where it is from.... It has an e-fan I am having trouble with. It keeps running at high temps. while in traffic. The fan and wiring harness appears to have been purchased at Auto Zone or advanced auto. I do not know much about the setup and would like some help if anyone is willing to give it.
