Not sure if this is the right place but.....

I'm running one of Nick's Hot Tunes and was wondering if towing a 12,500 fifth wheel will hurt anything? Should I just install a tow tune? I hate to keep going back and forth between tunes. Thanks

I would ask Nick since he knows his tunes better. But it may depend on the type of road. If hilly and steep grades u might end up running some high EGTs plus may shift more. Normally a tow tune is designed to maintian lower EGTs and to help keep shifting so much. Being you have a built transmission it probably not be a big deal. I just not hammer it to get infront of someone to turn right at the next light.

I cant tow with my "hot" tunes.

I tow with a +188 custom tune. It's all in your own discipline.
