ughh 6.4 problems
first off hey guys, i picked up a 6.4 in august and am pretty unhappy with it this far, hopefully a few of you can help me.
it has a spartan tuner with everything up to the 310 aggressive tune, freakin awesome compared to my ol 12 valve (may she rest in piece), an i have a 5" straight pipe with no DPF.
with the tuner on the 310 tune drivin easy so i dont roast the trans i can maybe get 16-17 mpg's on stock it will get maybe 13... my cummins with a full gravity wagon would average 15 all fall, without the power i guess.
i use the truck on the farm so there is almost always a trailer on it fall an spring so this fall i didnt care about the milage thinkin it was because the trailers, but weithout its doing no better, also i have gone through 3 radiators the dealership cant tell me a damn thing an pretty much rape me everytime i go there...
any help is appriciated if i cant figure anything out im thinkin about tradin for a common rail 5.9 please no bashing i just want some awnsers
