Has anyone got a Smarty Jr. loaded with the latest software, running on the highest setting and pulling a heavy 36 ft. fiver. I have been using the tow setting at 70 hp, no more smoke. The tranny has been gone through completely by Browns Diesel and given all the Gorand goodies. Shifts great, pulls the fiver great, and concisely gets about 11 to 12 mpg with the fiver in tow.
I wonder if it will give any better milage on the higher setting? By the way, I don't flog it when I'm hooked. Just slowly give it what it needs to get to track speed on the interstate.
