14CUX NAS spec chip upgrade 4.6
This software is intended for the 4.6 Lt engine, where the car is still using the standard Lucas 5AM airflow meter and standard Land Rover ERR722 fuel injectors.
What do I get?

What do we recommend?

- We recommend upgrading your fuel injectors
- Upgrading your MAF to the GEMS 20AM unit is recommended
What are the benefits?
- 10-15 BHP power increases with
- Improvements in fuel economy of 10-15%
- Better response above 4500RPM and removal of the "flat spot" on full load between 1750 and 3250RPM
- Improved idle speed, idle stability, shift patterns, cold starting, crank fuelling, rev limit (6500rpm), etc.
- Improved engine acceleration via the ECU configuration, to make it more responsive
- Service and fault diagnosis procedures are unaltered, and the upgrade is undetectable to Land Rover TestBook, Autologic, Rovacom or Lucas/Sun PDL test equipment
