About These Overlays:

These overlays have been tested with over 100 hours of validation and guarantee a complete solution with no blocked faults in the block fault tables. Achieving this requires anywhere from 700–2,300 individual parameter changes per overlay. These files are developed in-house and are not available from any other source.

Recommended for advanced users who understand how to use overlays and have access to the correct matching configuration files. No support or instructions are included — these files are for professionals who understand the full process of backing up and restoring truck parameters, unlocking the ECU, and the correct flashing procedure.

Purchase Options:
