My dad wants to add a chip to his pickup to get a little more out of his 4.6 for pulling his camper. Which chip would give him the best results? Thanks for the help.

 

Either brand will give the same gains. 24hp and 35 ft/lb torque.
Diablo is a bit less troublesome with the bracket lip on the
F 150 based vehicles.

Thanks
