well after spending 55.000 on my new longhorn and seeing a dismal 15 mpg i bought the H&S mini max and deleted the dpf and removed 100 pounds of EPA junk! now at 18.2 mpg and i can live with that. my last 5.9 averaged 20 mpg. so my question now is how do i complete this by deleting the EGR cant find anything on it in the instruction manual. all help appreciated.
