Pro LSX Swap or DOD Email Base Tune

Pro LSX Email Tune 

Bring your LS swap to life with a custom Pro LSX base email tune, built specifically for your engine, cam, injectors, and supporting mods. This tune is designed for startup and drivability — ideal for first fire-up and basic street testing.

What’s Included:

• Custom base tune file (.hpt format)

• Tailored for:

  • Engine size & generation (Gen 3 or Gen 4)

  • Camshaft type (stock or aftermarket)

  • Injectors & throttle body setup

  • Fuel type and system (return/returnless)

  • MAF or Speed Density operation

What You’ll Need:

• HP Tuners MPVI2, MPVI2+, or MPVI3 interface

• HP Tuners VCM Suite (free download from HP Tuners)

• A Windows laptop

• 2+ HP Tuners credits (not included)

How It Works:

1. Purchase this tune

2. You’ll receive a link to our Pro LSX Tuning Form

3. Follow the instructions to:

   • Upload your stock .hpt file

   • Provide build details (engine, cam, injectors, etc.)

4. Receive your base tune via email within 1–2 business days

Important Notes:

• This is a base tune meant for startup and basic drivability

• Not a dyno or full performance tune — final tuning is recommended locally

• Aftermarket injectors require a matching data sheet

• All tuning is for off-road and race use only
