    It did smooth out the shifts & gave ability to adjust electric fan but it did not give the ability to remove Torque Management. That was a disappointment. I updated it prior to install. Had to load tune twice to get to take. Overall it is ok. Only tried the 87 octane tune so far. I'll try the 91 before long.
