Gen 3 LS Swap PCM Tune Service (1999-2005) | VATS Delete | Torque Management Removal

$80.00


Upgrade your Gen 3 LS engine swap with a professionally modified PCM tune designed specifically for swapped LS applications. This mail-in LS PCM tuning service removes common factory restrictions and prepares your ECU for standalone operation in your project car, truck, hot rod, drift car, off-road build, or race setup.


Compatible with 1999-2005 Gen 3 LS PCMs including LS1, LS6, LM7, LQ4, LQ9, 5.3, 6.0, and similar GM LS-based engines.


Included in the LS Swap Tune Service:

  • VATS (Vehicle Anti-Theft System) Delete
  • Downstream O2 Sensor Removal
  • EVAP Delete
  • EGR Delete
  • Torque Management Reduction or Removal
  • Base Performance Spark Timing Adjustments
  • Power Enrichment Adjustments
  • Transmission Type Changes
  • Engine Size Calibration Changes
  • Flex Fuel Activation
  • Lean Cruise Enable (when applicable)


This base LS swap tune is designed to safely improve drive-ability, throttle response, and power output for most stock or lightly modified setups. Typical gains can range from 40-60 HP depending on your combination and supporting modifications.


Transmission Compatibility


Torque management settings can be customized based on your transmission setup:

  • TH400 / 4L80E / Manual Transmission – Torque management can usually be fully disabled
  • 4L60E / TH350 – Recommended torque reduction only to help protect weaker transmissions
  • Manual Transmissions


Please include whether your setup is:

  • Drive By Cable (DBC)
  • Drive By Wire (DBW)


Your PCM generally must remain the same type it originally came with unless using a 2003 Express Van PCM, which supports both configurations.


Camshaft Setups


If your LS engine has an aftermarket camshaft installed, I can adjust idle airflow settings to help the engine run and idle better. However, a full dyno or in-person custom tune is still highly recommended for proper fueling and drivability optimization.
