I have been running around 400 hp since the 100,000 mile mark. The Triple Dog has been set to Tow mode with low end torque setting. No issues yet and I passed 385,000 mile mark. Once awhile I do crack the extreme setting. I also use an additive in my fluid from Muscle.

I just hit the 30k mile mark on my truck. I have had the lift and tires since 5k miles. I have had the smarty (sw9) and turbo since 18k miles. I have no slipping issues whatsoever. I flush and serviced tranny at 25k and everything looked good. I am hard on the truck but I dont do any boosted launches or burn outs.
