i went back to 9r11 after the last update in may.. Power and fuel mileage was not there w the 9r14
9r11 seems to have the best balance of all with power and fuel for me--i use tow tune only--pulling 8-10k cargo trailer loaded getting 11.5 and 16-17 just driving around--2006 F350 duel wheels super duty crew cab
would be nice if 9r11 could be reverted back to as the base that updates from this time forward were done--as it seems something has been lost in translation since early 2010 when this update came out
yes--9r14 was very sluggish and lost 1to 1.5 towing and between 2-3 mpg just driving empty--needless tp say 2 weeks was all i could stand so i went back to 9r11
