OEM D200/D250 to D300/D350 POWER UPGRADE (L663)

Our factory power upgrade is configured the exact same way as the initial end-of-line software calibration that every vehicle receives at the time of build during the manufacturing process. Every new generation L663 D6H Ingenium Land Rover Defender shares the same hardware, therfore no physical hardware modifications are required to upgrade to the highest specifications. 

All of the parameters within the electronic control modules will now match like for like as though this vehicle was originally optioned as a D350. 

WE DO NOT OFFER THIS REMOTELY WITH NON-OEM SOFTWARE. 

WE OFFER A MOBILE SERVICE DIRECT TO YOUR PREFERRED LOCATION USING GENUINE JLR SOFTWARE. 

This software upgrade is not just for show, it drastically changes the vehicle power delivery giving the driver and their inputs more feedback and feel with a shaper response from the powertrain. With the additional torque increase under normal acceleration, the mid range performance is much more balanced allowing the gearbox to be in the optimal gear more often with less gearshifts needed. This is exactly how the engineers intended the D350 varient to feel in comparison to the D200, D250 or D300, which are all essentially a detuned version of the high spec model.
