ok so ive been running this chip since this summer(mainly because i got a great deal), but lately ive been wondering if there is an economy setting. With my big intake that i currently have, dumping smoke is nearly impossible, so i just stick to trying to conserve diesel. But...this summer before i added the big tires my best milage was about 18mpg on the freeway. Granted that i need a camber kit and a front end alignment, i was just wondering why my milage sucks compared to other 4x4 obs trucks with 4:10 gears? Is there an economy setting on the ts chips? Cuz the 75hp setting doesnt exactly economize...
