        Frequently Asked Questions

        Will this void my vehicle warranty?

        No. Unlike 'tuners' that rewrite your truck's software, the Woinex™ is a passive device. It leaves no footprint on the ECU and can be removed in seconds to return to stock.

        Does it work with the new 10-speed transmissions?

        The Woinex™ is designed for 6-speed and 8-speed GM transmissions. It does not currently support the 10-speed models or 2022+ 'Refresh' trucks.

        Will this drain my battery if I don't drive for a few days?

        Not at all. Our integrated Smart Sleep Mode detects when the engine is off and enters a low-power state to protect your battery life.

        Can I use this in California?

        While the Woinex™ operates within standard emissions limits, it is currently not legal for sale or use in the state of California.

        How do I know it's working?

        Once plugged in, your dashboard display will show that you are in V8 (or V6) mode constantly, even when cruising at highway speeds where it would normally drop to 4-cylinders.

          Smoother than stock

          "My 2019 Silverado drives completely different now. The V4 mode was causing a slight vibration I'd gotten used to. First drive after installing this and I can't believe I waited this long."

          Travis M. — Phoenix, AZ

        • ★★★★★

          My mechanic approved it

          "I asked my mechanic before buying and he said it was the smart move. AFM is known to kill lifters. He actually asked me where I got it after seeing it installed."

          Derek S. — Atlanta, GA

        • ★★★★★

          Perfect for towing

          "I tow a boat every weekend and the constant V4 switching was driving me insane on the highway. This thing fixed it immediately. Towing feels solid and responsive now."

          Chris W. — Tampa, FL

        • ★★★★★

          30 seconds to install

          "Pulled into my driveway, plugged this into the OBD port, started the truck. Done. It was in V8 mode the whole drive to work the next morning. Couldn't be simpler."

          Brandon L. — Houston, TX

        • ★★★★★

          No more hesitation on the highway

          "Every time I accelerated to merge, the truck would hesitate from switching modes. It was genuinely dangerous. This eliminated it completely. Should have been a factory option."

          Kevin P. — Charlotte, NC

        • ★★★★★

          Feels like a new truck

          "I have a 2015 Tahoe with 140k on it. I thought the shudder was just age. Plugged this in on a whim and I swear it drives like it did when it was new."

          Gary N. — Denver, CO

        • ★★★★★

          Gift for my dad — he called me immediately

          "Bought this for my dad's Sierra. He called me an hour after it arrived to say it was the best gift I'd ever given him. He'd been dealing with the V4 lag for years."

          Tyler B. — Nashville, TN

        • ★★★★★

          Every GM truck owner needs this

          "I've owned four GM trucks over the years. The AFM system has always been my one complaint. This is the solution I've been waiting for. Clean, simple, does exactly what it says."
