Is it worth the money for a predator stage III chip to put on my newly purchased completly bone stock 04.5 diesel HO 600 series engine? Its a quad cab , 2wd, 4 speed automatic. I can get a brand new one from a buddy for $50 bucks and wondering what your guys thoughts are on it. I won't be doing any extreme towing except maybe a bumper pull camper every now n then for a 200 mile trip.
