Boost Your Land Rover’s Performance & Increase Fuel Economy

A Monster Remap is an individual, customisable tuning service that is available for most modern Land Rover models, and most other manufacturer makes and models too.

A Monster Remap will increase performance, improve fuel consumption and deliver a smoother power delivery as a recent client found out.  This Land Rover owner brought his Discovery 3 TDV6 in for a Monster Remap and EGR Delete to achieve more power, torque and smoother power delivery. He was over the moon with the results we achieved.

Key Benefits

  • Engine becomes more responsive with a smoother power delivery.
  • Easier driving with less gear changes & improved acceleration
  • Safer overtaking, increased low end torque means less throttle is required – which results in fuel savings (most effective on turbo-diesel engines where a fuel saving of 10% is typical, but can be up to 20% if driven sensibly!)

It’s Legal and it’s Safe

There is nothing illegal about tuning or remapping, although you should inform your insurance company of any alterations made to the vehicle.

All modern, well serviced engines and maintained cars are perfectly capable of handling the extra power. However, if your engine is not operating as it should, or there are already problems. then a remap could highlight these faults. We always carry out a fault code read beforehand and advise any faults are rectified before a remap.

After a remap you should feel an immediate improvement. If you want the best economy, try and drive gently using the extra low down torque. If you take advantage of the power and drive hard all the time, we recommend more frequent servicing using high quality lubricants. Using premium fuel and/or a fuel additive will also help with performance and economy.

This is a remap service is carried out at our premises, located in Northamptonshire, just 2 miles from Junction 9 of the A14.

    Dear Sir
    I presently own a Land Rover discovery 2 TD5 (15P) Auto 53 plate, I have the following modification:
    – High flow air fliter
    – High flow intercooler (Serco)
    – EGR removed
    – De cat and performance exhaust- Power Flow Wellingborough (Due to be fitted shortly)
    – Heavy duty torque converter and up grade gearbox all ready fitted – Ashcroft transmission (this is the reason why I need a power up grade (170/180HP)

    I will be using the vehicle for touring so I am looking for a balance between additional power and fuel economy.

    Please can you advise if you can upgrade and the potential cost.

    Kind regards
