From what my friends say quadzilla is the best chip for the 98.5-2002 dodge diesels. he said the best chip for the high pressure common rail cummins is the smarty chips. but yeah i would love to have a diesel too
now i know it is possible to get realy good milage out of a diesel but your numbers dont add up.
i heard of a powerstroke getting 30 mpg with a predator tune propane and meth with an double overdrive splitter but that all clost like 10g to get and time too install so i guess it will pay its self off but not anytime soon. also this trucks only use is looking cool and good milage
