Custom Tune?

[sjp649]

Hi,
I just want to start with, I love this programmer, lots of power and torque, the only part I don't like is the mileage. I have a 1999.5 7.3 long bed crew cab 4x4. I'm getting about 13.5 in the city, and 15 on the highway(hand calculated) I have the tuner on 100hp, I've tried 60 and 85 and they are no better, my best milage has been on 100 driving like granny. I have 4" exhaust from the turbo back with a magnaflow muffler and 5" tip. Homeade tymar intake(donaldson filter) boost fooler. I tow a 36 foot fifth wheel toy hauler whice weighs close to 10,000lbs. It tows it good in either the 40, 60, or 85 tune, I do get a lot of turbo surge though when climbing overpasses. I have a wicked wheel to install still. Do you think I should have a custom tune done for towing that beast, and maybe one for better mileage? Revision 7r19d Cal ID VJAE3US

Thanks,

Steve
