So, it has been a while since I have updated this page.

To catch everyone up I replaced the cluster with a dorman unit. It has a lifetime warranty and works great. I went through summit and if i had to do it again I would go straight to dorman to try and speed up the time frame. Through summit the refund took a few days longer than I thought necessary.

I also got around to installing the electric fans they literally bolted right in a couple of existing threaded holes in the cross member and they work great! they are hardly ever on, but with the summer heat they keep my engine temp at a constant 200ish degrees. I have not noticed any significant increase in throttle response or mileage increases like some claim but I guess every little bit helps. The engine also gets up to temp quicker.

For MPG numbers after the fans, exhaust, Intake and most importantly the computer tune are as followed:
In town at varying speeds 13 mpg (up 2 mpg) is the norm, on the Highway at 65 mph it is around 18 mpg (up 4 mpg) and on the interstate at 75 mph it drops to about 16-17 mpg depending on the day (up 3 almost 3 mpg).

I am thoroughly impressed with the efficiency numbers and love everything about this truck.

Next project is to upgrade the trans cooler! on the 4th of July towing a toy hauler the trans got a little warmer than I am comfortable with pulling some of the mountain passes. I will post pictures when i get it done.
