The Tahoe runs so much better now. I don’t have to actively shift not 5th gear on the freeway to avoid the super annoying 4 cylinder DOD mode.

Unlock the full potential of your GM engine. This plug-and-play device keeps you in full-power mode 100% of the time, eliminating annoying throttle lag and protecting against expensive lifter failure.

  • Full-time V6 or V8 power with zero lag
  • Leaves no trace on ECU for total warranty safety
  • Plug and play setup works without any tools
  • Smooths out driving by stopping vibrations

Question 1: Will this device void my vehicle warranty or leave a permanent record in the computer?
Answer 1: No. Unlike traditional performance tuners, this device does not reprogram your factory ECU. It works in real-time while plugged into the OBD-II port. Once you unplug it, your vehicle immediately returns to its original factory settings with no digital footprint left behind for a dealership to find.

Question 2: How do I install the device and confirm that it is functioning correctly?
Answer 2: Installation is completely plug-and-play with no tools required; simply plug it into your vehicle's OBD-II port under the dashboard. Upon connection, the blue lights will flash in sequence and then turn off, which confirms the device is active and successfully keeping your engine in full-cylinder mode.

Question 3: Can I leave the device plugged in if I do not plan on driving my vehicle for an extended period?
Answer 3: To ensure your vehicle's battery remains at its optimal charge, we recommend unplugging the device if the vehicle will be sitting idle for several days. While the device is designed for daily use, removing it during long periods of inactivity prevents any unnecessary battery drain.

Works Perfectly, easy install I've put about 1k miles on my truck with this on since purchased. Always stays on v8 mode. No lag. I drive a 2015 5.3 gmc sierra. I haven't experienced no battery drain, it seems to shut off with the vehicle.(blue lights) seems nice and durable.
