How can I increase the HP and TQ in my Dodge 4.7 V8? Is there such a thing as a processor...?

It`s pretty well maxed out as it is, I would not try and get much more out of it. What vehicle is it in and what is the problem? Sludge problems have all ended up being poor maintenance issues causing the build ups and poor cooling/overheating. Owners fault, not a manufacturer defect
