Range Technology Active Fuel Management

I have a 2015 2SS Camaro with auto trans and L99 engine W/AFM. Fart Mode was less noticeable with the stock exhaust. Once I put an axle-back system on, the fart mode was very noticeable! Something had to be done about this!! Not wanting to void my warranty with a tuner, I needed an alternative. Enter the Range!! Plug it in and AFM is completely disabled. Pull it out and fart mode is back and the Dealer will never know if you need service. It is well documented that AFM does not save gas and it does more harm to the engine than good. Take back your vehicle with the Range. Get a full time V8 and avoid blowing up your motor. Win/Win!! I have been using the Range for a couple of months in my Camaro and it works well. I drive the car daily, so I do not remove it. If the car was going to sit for several days, I'd remove it until I drive the car again. The Range works as advertised and disables AFM immediately after you plug it in. Now much else it say. I recommend the Range to anyone looking to disable AFM and protect the health of their engine. EDIT: A few months after publishing my initial review, I need to take back a few wonderful things that I said about the Range. FIRST: It still works as advertised, BUT there are some undesired side effects! With the Range installed, one time my Camaro would not start or do anything when I turned the key all the way. It acted like the battery was dead. I pulled it out, then the car started, but the check engine light came on. Took the car to the dealer, and by then the computer had healed itself and there was no code. It happened again once about a month later, but no check engine light. Today, the car would not start. Pulled out the range and it started, but the power steering had an error and was not working properly, the Brake light, ABS light, and check engine were also on. Drove it a few miles, shut it off and everything cleared out and the power steering started working again. My friend has a Range and has experienced similar issues. I have down-graded my original review from 5 stars to 2 stars.
