Power upgrades are engine-specific rather than model-specific, but not every engine is available in every model. The table below shows which Jaguar and Land Rover models can receive each factory power upgrade.

If you have researched power upgrades before, you have almost certainly encountered remap companies promising huge power gains for low prices. It is important to understand the fundamental differences between an aftermarket remap and a genuine factory calibration upgrade — because they are not the same thing, and the choice you make can have significant consequences for your vehicle's reliability, warranty, and resale value.
| Factor | Factory Calibration (Our Service) | Aftermarket Remap |
|---|---|---|
| Source of calibration | Official JLR engineering database — identical to production-line files | Third-party modified version of original file |
| Engine safety margins | Uses factory-tested limits designed by JLR powertrain engineers | Often pushes beyond safe limits to achieve headline figures |
| Warranty impact | No impact — dealer equipment reads it as a legitimate factory file | Will void powertrain warranty if detected |
| Dealer detectability | Undetectable — appears as standard factory calibration | Often leaves checksum mismatches and flash counters |
| Reversibility | Fully reversible to original calibration at any time | May corrupt original backup; not always fully reversible |
| Emissions compliance | Maintains factory homologation and emissions certification | Often removes or alters emissions controls illegally |
| Service intervals | Unchanged — recommended by JLR for the higher output variant | May require shortened intervals due to increased stress |
| Resale value | No impact — documented as genuine upgrade | Can reduce value; buyers and dealers actively avoid remapped vehicles |
The bottom line is simple: if you want more power from your Jaguar or Land Rover, a factory calibration upgrade gives you the performance you want with none of the risks associated with aftermarket tuning. You pay a little more upfront, but you save potentially thousands in warranty disputes, premature engine wear, and diminished resale value. For a vehicle that likely cost tens of thousands of pounds, it is the only sensible choice.
No. Because we use genuine factory calibration files that are indistinguishable from production-line software, dealer diagnostic equipment cannot detect any aftermarket modification. Your powertrain warranty remains fully intact, and in the extremely unlikely event of an engine issue, there is no evidence of tuning for a manufacturer to dispute.
No. The calibration file we install is an official JLR file with valid checksums, correct version signatures, and no flash-counter anomalies. When a dealer scans your ECU, they see exactly what they would see on a vehicle that left the factory with that power output. This is the fundamental difference between our service and an aftermarket remap.
The exact gains depend on the upgrade you choose. Our D165 to D200 upgrade adds 41hp and 50Nm. The P200 to P250 adds 50hp and 45Nm. The D300 to D350 adds 50hp and 50Nm. For PHEV models, the P440e to P510e adds 70hp, and the P460e to P550e adds 90hp. These are real, measured, factory-verified figures — not theoretical maximums or optimistic dyno claims.
Yes, completely. We keep a secure backup of your original calibration file. If you ever want to return your vehicle to its factory power output — for example, before selling or leasing return — we can restore the original file in under an hour. There is no permanent trace that an upgrade was ever performed.
In most cases, fuel economy remains very similar to the original output because the factory calibrations are optimised for real-world driving rather than dyno figures. Some customers actually report slight improvements in motorway cruising efficiency because the higher torque allows the engine to operate at lower RPM. However, if you use the extra power aggressively, consumption will increase accordingly.
