I have about 110000 mi. on my 02' and just installed a superchips max tuner. It says on the box not to pull anthing with it on the highest setting which is only 70 hp. I pull 10000-25000 lbs. every day and I was wondering what the big deal is about 70 hp. because most of the guys that I haul with have 80-100 hp. chips, injectors, or both with no problems. any opinions would help. Thanks, Dustin
