If for towing, get a nice header to peel heat quicker. Adding fuel will just heat things up in a jiffy... Also, think about at minimum a Raptor if you are running the stock lift pump. Anything over stock will kill it. After this, throw some 75 - 100hp sticks in there and if budget allows, look at a Smarty or Edge.... My next turner will be the Smarty so I can get the high idle set up.....
