An EFI Live delete kit combines an EFILive AutoCal V3 flash device, custom tuning files, and physical exhaust or EGR components to remove factory emissions equipment on diesel trucks.
What Is Included in the Kit?
EFI Live AutoCal V3 Device: A portable hand-held flash tool used to download and transfer custom calibration files directly into your truck's engine control module (ECM).
Custom Tuning: Software modifications designed to disable monitoring logic for removed hardware, eliminating error codes, check engine lights, and regen cycles. Many kits support Switch-On-The-Fly (SOTF) power level adjustments.
Delete Hardware: Typically features a straight DPF (Diesel Particulate Filter) race pipe or a full 4-inch/5-inch downpipe-back exhaust system, alongside block-off plates for the EGR (Exhaust Gas Recirculation) valve and cooler.
Systems Removed or Deactivated
DPF & CAT: Replaces restrictive filters with freer-flowing pipes to lower exhaust gas temperatures (EGTs) and improve fuel economy.
EGR System: Deactivates exhaust gas recirculation to stop carbon buildup in the intake.
DEF & SCR: Eliminates the need for diesel exhaust fluid injection on modern selective catalytic reduction systems.
Key Considerations
Intended Use: These packages are engineered strictly for off-road and competition use. Removal of factory emissions equipment violates federal and local clean-air regulations for public highways.
Warranty Impact: Installing these modifications will typically void your vehicle's factory powertrain warranty.
Computer Requirements: Loading custom tunes onto an AutoCal device initially requires a Windows-based PC with the EFILive V8 software installed.
Pricing and Cost
Complete packages typically cost between $1,050 and $1,724 USD. Prices vary based on your truck's make, model year, whether to include SOTF, and upgraded exhaust configurations. You can explore specific setups below.
