I own a 01' 7.3 love the truck but tired of getting stomped by these dmaxes which are big around this area but the thing is.... im a FORD guy and dont want to make that kind of stupid switch. Any HP/torque story out there with supported mods. Any other info or tips out there to take into consideration b/c I want all the hp/torque I can get but I want some fuel mileage good to.
if you get a 6.4 put 1500$ into it with tuner, cold air intake, and dpf/doc delete you will be pushing 600hp and I believe 1200 tq. there is a post in the performance with a guy beating a new model ss camaro so, to answer your question yes you will smoke a dmax. If you have the money these trucks will make huge power, just be careful there not as durable as your 7.3, but thats not saying much you can damn near run rocks through the fuel system and water for oil on a 7.3 and you will be fine, the 6.4's are still great trucks.
