Review on Revolutionary NEW RANGE TECHNOLOGY AFM-DFM Disabler for V6 & V8 GM Motors in Vibrant Blue by Jorge Kumar

It does what it says it does but on more than one occasion my truck has gone back to V4. You can't see the light, but if you put your hand under it while driving, you can see the light glowing on your hand while it's working. When I noticed the truck wasn't on fire in the V4. As soon as I stop, I turn off the truck, disassemble and replace it, the headlights come on and everything is as it should be. For the price of this edition it's not worth it. If it worked without this problem I would recommend it, but not if it decides when it doesn't want to work.
