Hey guys what the thinking on the best tune for a 6.4L with a Spartan for the best mpg and power? Thanks

310 Tune. :D But the HG's and transmission will have some issues if you beat on it with that tune.

Thanks Macbookn, although dont need the huge power, looking for best mpg. Still go with the 310?

I did dpf/cat delete, egr delete with elbow with the Dashdaq xl

Yes. The larger tunes, if driven easily, will yield the best MPG. The 310 can be very touchy, so if you find yourself accelerating to fast, drop down to the 275. The 310 has a little bit of a learning curve for daily driving.

Thanks I'll give it a try with the 275

275 is the best all around tune. Plus you can smoke pretty much all the little ricers from red light to red light.
