Truck runs great especially when towing. Lost a little fuel mileage but is well worth it.

Easy to install but be sure to follow instruction. (Pull proper fuses). Disconnect (8-4 cylinder) drop out. You will have a smother , quieter and more responsive engine. There are also two options to try the premium option and the regular option I have yet to try their premium option but I am very satisfied with the regular option. For my money it was well worth it.

AutoAnything had fast, on time shipping and great packaging. Had a little trouble installing the programmer due to some aftermarket mods(remote start). Eventually got installed by removing some fuses and is now simple to do when switching to a different tune. Saw instant gains in MPG, around 2.5 MPG on economy tune. Also some noticeable torque, power, and acceleration gains on economy which is what I have it on most of the time. Bought mostly for better MPG and did just that.
