DO NOT RUN EITHER WITHOUT A PYRO/EGT AND A DEDICATED TRANNY TEMP GAUGE. THE REST IS UP FOR DEBATE. i HEAR SOME OF THE EXTREME / LOONEY TUNES (EITHER OR) run HOT ! But hat is in Performance Setting not TOW. JUST watch your gauges and know the factory tranny gauge is a Dummy gauge..
I use Eric's street tune to tow with and it has to be a long hard pull to get it to 1200*. The only reason I got that hot was I was experaminting to see how hot it would get, left it in 6th gear and pushed it a little more than normal. I always pull in 5th gear when climbing a grade and it will cruise up any hill at 60-65mph and not get over 1000*.
