i have bought a smarty jr and have been running it on the 70 hp setting for about a month.everything is stock except the airfilter.I was wondering when i hook up my fifthwheel which weighs 7000lb dry could i run into trouble. also its a 6 speed tranny.and if not could i go to 100 hp setting.

 

you can try it on the 70hp setting. . .however be very carefull as too much throttle may slip the clutch. if you do notice the clutch slipping easily go to a lower program.

FYI. . .my stock clutch is able to hold smarty on the 130hp setting and my TST on 4/1 for a combined approx 500hp. it put me sideways on the interstate and I was already doing 50mph
