| Right now I am just using my TST Powermax. I normally use it set for 3 hp and 3 tq (about 45 hp gain over stock). Around town I get 14-16, on the highway I get 18-19, and towing a 24' V-nose enclosed trailer I get anywhere from 10-14 depending on temp outside. The best mileage towing came from when the temp was around 25-30F above. My towing numbers are on winter fuel with stanadyne added. I am getting ready to tow again this weekend....I should be towing a 32' camper...hopefully I can get around 12-14.
