I have already tryed asking in another section and tryed a search but came up with nothing. Has anyone added a chip, module, dpf or egr deletes, water meth injection, MP-8 fuel rail shim, bully dog programer or anything that would increase mpg. Performance wouldn't be so bad awell. I get 15mpg on average and less when driving around the city. I am carring a full load at all times. I think I am definetly over the weight limit.
Thanks
