Product Info

Compatible with:

Duramax 2004.5-2005 LLY
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.

    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.

    All sales are final. If you want to cancel your order after it has been placed but before it has been processed or shipped, a 10% Cancellation/Card 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.

I absolutely love my kit. Same fuel mileage and power from stock. Nothing changed there. But still love not dealing with the mechanical issues DEF was giving me.

Josh

07.5-09 RAM RACEME ULTRA Tuner & Tunes

Didn't see any improvement in fuel mileage,but I am pleased with product and the prompt shipping, everything worked smoothly and it was nice being able to actually get in touch by texting before I ordered product as well, I kinda of wished I'd ordered the muffler kit but it doesn't sound half bad with just straight pipe

Travis

Elliot

Great price! Quality parts! Worked as expected! Very faster delivery.

Richard

11-14 Ford 6.7L EGR Delete Kit

Very happy with the product. The tuning is good and the kit was everything I needed. The stock 4 inch into 4.5 was the only issue with the deleted pipe but easily fixed with a new adapter.
