Can a tune be written for economy on the HWY?

That is correct for my truck and tunes. BUT every truck is different and every custom tune is different. One reason the tow tune works better for me in the city is that I have highway gears (3.55 LS) and larger than stock tires. This combination works against me because due to gear ratios I am at a mechanical disadvantage. I like the tow tune for stop and go because the extra torque helps to overcome this disadvantage. My tow tune is also written with a pedal position map that is less aggressive than stock (for off road use) so the truck is not as jumpy.
