Hey fellas i got a couple questions. First i have a htt turbo and efi live . i am gettin ready for a trip to california in three weeks . i will be towing a 48 foot goosneck that will be close to 10 ton. It tows fine however i am gettin about 10-12 mpg with this. Does this sound about right and also would i benefit from another tranny cooler or is it a waste of money. I have a suncoast stage four or will i be fine with what i have. any advice would be greatly appreciated.
