I've got a 2000 5.4 Expy and am towing about 6000# and need to stay in 3rd gear to maintain 65mph, getting a approx. 7.5 mpg. I was researching the Superchips programmer and it states that it will adjust shift patterns and has 3 settings:
87oct. w/towing
91oct. w/Towing
91oct. perfromance no towing.
I guess my question is does anyone use the above model or a similar one with equal settings? If so, are the hp/torque gains dependent upon what setting you are in? Is the programmer worth the money?
That 7.5 mpg is on the flat land and I'm terrified how bad it will be when we take hills.
