I purchased the tuner to disable the AFM/DoD function that bumps the engine down to 4 cylinder operation. I found that the older my vehicle got, the more lag it would have off the light. This tuner changed it all. I started running a 87 octane tune and already noticed a huge difference in driveability, throttle response, and shifting. It was like a whole new truck. Now running 93 octane tune, the difference is amazing.
