During a 300-mile trip, our Yukon managed to maintain a decent 17.5 MPG with AFM. We were prepared for the usual uptick in efficiency, but we weren’t disappointed when it stayed steady during the return trip. the fact that AFM usually kicks in less on highways didn’t seem to be an issue for us anymore.
We’ve encountered a few hiccups along the way too. One user shared their experience with a 6.2L Camaro-they noticed odd ABS and brake lights illuminating, with an occasional bouncing tachometer after a week of inactivity. After unplugging and replugging the device, the issues resolved, but it left us thinking. The users praised the maintenance of V8 operation, which means no more cylinder shutdowns that typically put wear and tear on the engine.

For instance, on a long trip, our GMC Yukon averaged around 17.5 mpg with AFM activated. After switching to full-time V8 mode, we observed that our fuel consumption remained relatively stable. It seems that while the device keeps the engine in V8, which might suggest higher use of fuel, the comfort and smoothness in power delivery compensate for any additional consumption. This efficiency balance keeps us feeling good behind the wheel.
One thing to note about power and fuel is battery consumption. Some users have raised concerns about the device draining the battery if left connected for extended periods when the vehicle is not in use.From our experience, while it’s important to unplug the device during long storage periods, we didn’t notice any important battery drain during regular use. A helpful tip would be to install a power switch if you’re often leaving your vehicle parked for days or weeks.

A: By disabling the 4-cylinder mode, we’ve noticed that while you will have more raw power available, it may lead to decreased fuel efficiency compared to when your engine switches to the 4-cylinder mode for highway driving. If you prioritize performance over fuel economy, this trade-off might be worth it for you.
Q6: Is there anything we need to keep in mind when using the device?
A: Yes! If you don’t use the device for an extended period, it’s recommended to unplug it to avoid draining the battery. Also, be sure to keep an eye on the blue flashing lights upon installation to confirm that it is working properly.
