The Nissan Path

Hey yall, got a bully dog triple gt a while back and was wondering what some of yalls opinions were on which setting I should run for best power/mpg gain. I'm running a 2" lift and 285 trail graps (they're pretty heavy), so I was thinking of tuning it for power to balance out the mpg loss I suffered. However, the towing setting, that may accomplish the same thing. My theory about the mpg booster mode is it restricts rpms and switches transmission timing to change at lower rpms as well, and with such heavy tires it really helps to just get it up to speed and then set the cruise. Anyways, lemme know some opinions on what yall are thinking about this type thing?

Thanks,
T
