[QUOTE="tbsimmons, post: 132565, member: 2026"] That is weird with Eric's tow tune. That thing pulls great for me. Boost will hit 41 and I have had the EGT's get over 1300 though passing a Duramax pulling about a 10,000# fiver going up about a 6.5% grade. One reason might be the gears though. I am above 2000 at 55. I have towed about 8000 or so tag car trailer with the street tune. I dont think I will try towing the fiver on it. TOO HOT for me. It was east for me to get to 1300 and I didnt push it too hard over flattest hills around me, held 60 on cruise just like I do on the tow tune. I dont think I could have pulled the car trailer to the beach, much steeper and longer hill. But yes the mileage is better. I dont know what hills you are climbing, but the ones that get the EGT's hot for me are not just steep ones, it is the ones that go on forever. [/QUOTE]
