Last December I ordered the F5 chip from DP. I finally got around to opening the box and installing it. It helps that I am no longer employed so I have time to catch up on the 1000 things on the list.

Five tunes. Stock, 40 Tow, 60 Tow, 80 Daily and Decell.

I spent about an hour doing the basic install and then test drove it. I must ask myself why I did not do this years ago. Any of the tunes make the truck go like stink. No need to buy a new truck now.

Now to get the dremel out and cut a hole in the dash to mount the switch.

Thank you DP-Tuner
