Hot? Yes
I tryies the superchip programer on the middle Performance Towing setting. I am also running factory RV275 injectors, the programing was simple, and the pwoer was up, not as much as the comp on 1x3 or 1x5 by a long ways. Yes the truck was running hotter on the pulls by 200-300 degrees, I drill the hole for the Scotty II and temperatures drop back a bunch. I like to try the perfomance not towing setting, but i believe it will be to strong for the Automatic transmission.
