Custom tunes ?

I am currently running RCD's 450 rwhp tune and have put 60K trouble free miles on my truck with this tune. Is there a tune with more horsepower that you can safely run in your truck as a daily driver and pull a trailer with it? I have heard about somebody named KEM and Innovative Diesel's Extreme Street tune. Are these safe to pull with. I don't wan't to stretch head bolts or ruin a transmission. Any feedback would be appreciated.

Gearhead Street and Hot Street tunes is what i run. I've towed 10K lbs with the hot street on 37's without issue. i guess it depends on how heavy you're towing, but i would reccommend giving Matt a call @ Gearhead. And i've run KEM 345 and all of IDP's tunes. Gearhead by far is the best IMHO. Good shifting, low smoke, smooth power.

Gearhead's street file is around 475 to the wheels and can do towing under 10k. That's the file I run right now on my dually. I've towed with it a couple times, the heaviest was around 7k.
