As with any performance upgrade you need to use your head. If you donot abuse the power everything will be fine but if you are doing alot of raceing or sled pulling you will need to upgrade your transmission and torque converter to handle the power. If you keep your settings below 80 Hp the Allison will handle it pretty well, but if you go above 80 Hp it will bite into the life of the transmission.Edited by: Diesel Tech
