recently bought a 7.3 obs powerstroke, ex cab long bed manual 5 speed 4x4. Its all stock as of right now. I need advice about very cheap but effective mods. lookin for better mpgs and for some more power. When i tried putting a friend superchip on it my truck wouldnt start... Not sure exact chip but it was a 75hp and he had it on a 96 powerstroke. Any help or advice is appreciated.
