Its very easy, it walks you through it while its plugged in, as for the thermostat, my friend baught the hypertech thermostat and not only did he not see a performance upgrade....his truck ran at the same temperature, you are perfectly fine with the stock thermo.
well i just tryed to program the truck and they gave me the wrong one, I have an 03 and they sent me one for an 01 and I go out of town tuesday and i really needed this so i am pretty pissed right now!!! :flame: :murder:
Well i dont really NEED it but I am going to garner tuesday and i live in houston, so I thought that it might help my truck with going through all of the hills and stuff, but mostly I just wanted it!!! I know that I probably shoulda got the nelson tune but i really dont have the money right now :bawl:
