Product Info

Compatible with:

Duramax 2001-2004 LB7
Product Description

These small switches offer big adjustability. By simply turning the dial left or right until it clicks, you are able to command your truck to give you more or less HP & TQ. This obviously only works if you have already flashed the ECM with SOTF tuning software. Depending on your vehicle, our switch will utilize your truck’s Fuel Temperature Sensor, Crank Case Pressure Sensor, or Intake Air Temperature Sensor.

Returns Policy

  1. General Return Policy:
    Due to the specialized nature of our products, we generally do not accept returns. Most items are VIN-specific or custom-built to order.
  2. Defective Items:
    We only accept exchanges for defective items. We recommend professional installation for these items. If a product is defective and cannot be exchanged or repaired, a refund of the original purchase price will be issued upon receipt of proof of malfunction or damage.

    In certain cases, we may make exceptions for returns. If your return request is approved, a 30% restocking fee will be applied. All items must be returned in their original packaging, and return shipping costs will not be refunded.
  4. Cancellations:
    All sales are final. If you cancel your order after it has been placed but before it has shipped, a 5% processing fee will apply.
  5. Non-Returnable Items:
    Certain items, such as hard parts (e.g., EGR kits, DPF pipes/exhaust, pyro kits, throttle valve kits, exhaust tips, and intakes), are not eligible for return unless an exception is made. If an exception is granted, a 30% restocking fee will be applied, along with the cost of return shipping.
