Got a 1993 d350 5.9 12v cummins all stock 37828 miles. Looking to make more power withput killing the fuel milage,i know --bigger turbu,injectors,turning up the pump,--but is there other ways to get more power and not kill the milage,this is my first diesel and just want more power,---not that it does not have --because it got some huevos,,i think it is a 2100 or a 2300 rpm eng,from factory and does not have a tach,can some one give me some tips on this please.
Thanks mike
