I tried this setting the other day for the first time. It was unreal how fast the truck was and how touchy the throttle was. Does any one know what the low end power setting does? I do understand that it makes it faster, but is it through "instant" boost or what? Thanks.

 

it tricks the computer in thinking the motor is at high boost and wants more fuel. and it also makes the throtle very senstive very hard on transmissions

 

Thanks. I took it back off and left it on the tow mode. It was fun while it lasted but was also hard on the tires, as they would not stop leaving long black marks on the streets.
