3.0 Diesel D200 to D300 Factory Power Upgrade
If you own a 2020+ Land Rover or Jaguar with the 3.0-litre Ingenium diesel engine, you might have the D200, D250, or D300 variant. What many owners don't know is that the D200 and D250 share the exact same hardware as the D300 — the only difference is the ECU calibration. You can purchase our power upgrade service to unlock the full D300 or D350 performance from your existing engine. Explore our factory power upgrade options for all compatible models.
What Is a Factory Power Upgrade?
Unlike an aftermarket remap, a factory power upgrade uses JLR's own ECU software files. These are the same calibration files that dealers use when ordering a higher-output variant. Because the software is genuine, your warranty remains intact and the engine operates within factory parameters.
