I've got a 6.7 with H&S MM w/OD tune, all deletes, Banks CAI, Glacier elbow w/inline htr, 425's with O-ringed head, big pans on trans & diff. I'm wondering about custom tuning to help with reliability. I don't want to pay for another head gasket, bigger turbo is not in budget and when it is it will most likely be a Fleece modded VGT for simplicity. I tow a TH and gross just shy of 27000 lbs. I like to be able to run 80 mph on interstate in OD running 2000 rpm and can most of the time unless there is a strong headwind or climbing. Any tuning suggestions? If so, can they be downloaded into H&S?
Thanks

 

You can have someone build you a custom tune

Who does this? What does it generally cost?
Thanks.
