[DFontaine]

hi all, 1st post. just bought a 07, 5. 9 4x4 auto, got rid of my 7. 3 powerstroke, which was a great truck, anyway what would be your 1st mod be for a truck that will be used for towing and long road trips ? would a pyro, boost and trans gauge be the ones? thanks

definitely gauges first!!!!!

Do the gauges first the transmission really needs one on it IMO. Then a good air intake and free up the exahaust should free up some hp for ya.
