Game changer…
Bought this for 15 yr old Suburban. With nearly 300,000 on the odometer, the change from V8 to V4 was very rough and caused a severe vibration in the truck. Now all that is gone and it never drove better. Plus, mpg didn’t change.

Range Tech
Bought this for my 2019 Chevy Silverado trail boss. I was nearing 100,000 and have replaced my lifters 2x and my camshaft once all under warranty. I have installed this device in hopes of eliminating future problems.Easy to install and this is an awesome device. I had my doubts with fuel efficiency, but I actually save money on gas!!!! I guess because it is more efficient staying in V8 mode rather than switching cylinders…suck it Joe Biden with your electric vehicles, I have a V8 truck and love it!!!

Works great on my 2018 Yukon Denali
Easy install! My 2018 Yukon Denali is now 100% V-8. One does not buy a SUV or truck for gas mileage but rather for performance. Small difference in gas mileage, big difference in performance! Also need to consider the issue of AFM lifter failure due to AFM stuck lifters…very costly repair.

Works Great!
Seems to be doing the job. Indicator lights are not visible on my truck (2015 Chevy Silverado) some I’m not sure why different color lights are offered.

Gets the job done
So far no drop off on MPG. It’s about the same maybe even a little better. My Suburban was using oil – about 2-3 quarts between oil changes and the dealer said this was “normal.” Anyone who knows something about cars will tell you that it is not normal for a modern motor to use oil. I have yet to verify (will update with results) but others are saying this eliminates the oil use, which was a huge inconvenience to have to constantly check. That alone is worth the cost. Also feel like the motor is running more smoothly without having to switch out of V4 mode at low RPMs. Nobody wants a 4 banger powering their 5500lb truck at any time. Glad to be rid of this curse.

Do not stand behind their product
Bought this product and it worked fine until just under the 1 year warranty period. Product stopped working so I contacted the seller they sent back with a serious of things to try did that and still does not work. Contacted the seller and advised but no response. The product worked well until just under the 1 year warranty period and seller did not stand behind their warranty and replace the product so it is definitely not worth the money I spent on this product. Purchase this with caution as seller does not stand behind their product!

This will stop your lifters from failing.

Works as described. Seems upside down when installed so you canât see the lights but keeps the vehicle in V8 mode just as described. Only one of the 3 lights illuminated when the vehicle is running not sure if this is normal or not. But hopefully this solves the collapsible lifter issue that gm and Chevy wonât address in Canada
