Hey guys I'am about to buy the Spartan tuner and was just wondering is the 250 hp. tune seam to be the one most of you run? When you are tuned to 250 and you go to tow something do you still use the Tow/Haul mode on the truck? What is the best tune for the most MPG's Not looking at really running any higher than the 250-275hp. Also it seems very complicated to load and store all the info. Is it really that hard for someone with not that much computor experiance, Thanks.

You will get your best fuel milage with the high hp tunes as it shuts the egr off as well. and truck is not working very hard to move. I have towed a fair bit with the 275 tune but dont recomend it if your worried about breaking anything. it is fairly stright forward to store the info and if you run into any problems spartan has very good customer service and will help you out.
