Deff plan for tow , economy , proformance , where mite one find a tranny cooler?Nice conversation you're having with yourself.
With regard to Uprev, be careful towing in a performance map. It may be too "hot" and can lead to overheating. Hopefully you ordered one of your maps as a towing map.
Since you're towing and are all-in on mods, consider adding an aftermarket transmission cooler.
