This requires the process of doing a stock read. A Windows computer is required for EFILive Scan and Tune Tool.

Elevate the performance, fuel efficiency, and longevity of your GMC Terrain or Chevrolet Equinox with our Delete Tuner. Our solution not only enhances your vehicle’s drivability but also streamlines its operation by eliminating unnecessary emissions systems. Here’s what our Delete Tuner offers:

• Custom Tuning with EFILive AutoCal V3: Included with our package is the EFILive AutoCal V3, a cutting-edge device that simplifies the tuning process. For precise calibration, 1.6L models require a vehicle-specific read file, ensuring our custom tune perfectly aligns with your car’s needs.
• Emissions System Removal Made Easy:
  • DEF Delete: Eliminate the dependency on Diesel Exhaust Fluid (DEF), reducing both maintenance frequency and associated costs.
  • EGR Delete: By removing the Exhaust Gas Recirculation (EGR) system, you prevent carbon deposits from impairing your engine’s performance and reliability.
  • DPF Delete: Enhance your vehicle’s exhaust flow by bypassing the Diesel Particulate Filter (DPF), leading to noticeable improvements in fuel efficiency and power output.

• Canbus Plugs are recommended for easier installation. The plugs bypass the NOx and particulate matter sensors. Some wiring is required to bypass the DEF Module

EFI Live’s Duramax User Guide

*The E98 ECM in the Colorado/Canyon/Equinox/Terrain/Gen 2 Cruze can be difficult to get the dash messages to clear. In most cases we can get these to clear with a reset tune and other strategies we have come up with. If you do have messages present before tuning we can’t guarantee that we can get them to clear but in most cases we can. Sometimes it takes returning to stock, clearing messages, then tuning.
