It works I can feel the difference on top end and throttle response is much better.

My dad found this for me because I was looking to get a little more out of my 2000 Monte Carlo SS. This is a great price compared to other programmers. The shipping took longer than "3 business days," and the installation took a long time. The instructions were mediocre, so a Chilton manual helps for the wiring diagrams, and tapping into the sensors was difficult with the included plugs. Overall I got a lot more performance and gas mileage out of my Monte Carlo, and the monitor function is cool to have.

Bought 2 of these after the 5.3L in my '08 Tahoe dropped 2 cylinders at 147K miles. Stuck them in my Tahoe (after a new engine) and '14 Silverado to make sure I don't have problems in the future. Maybe slight decrease in fuel economy, but doesn't appear to be much. Provides some peace of mind which makes it worth it for me.
