The most recent addition to the list of RENNtech tuned vehicles is the 2023 Land
Rover Range Rover. Powered by a 4.4 liter Twin Turbo V8 the factory published
power figures are 523 HP and 553 LB FT of torque. Tested on the DYNO at
RENNtech, the Range Rover produced 588 HP and 650 LT-FT of torque, 65 HP and 97
LB-FT more power than advertised.
The RPM is a “piggy-back” style ECU upgrade designed to pull additional power from the engine by adjusting fuel-to-air ratio, ignition timing, and throttle mapping through RENNtech’s proprietary software.
With RENNtech’s software, the Range Rover engine produces an
additional +57 HP and 40 LB FT of torque at the crank, delivering a totalof 654 HP and 690 LB-FT of torque!
With tune installed, the Range Rover feels equally smooth as before, but is quicker from the start with a stronger pull at higher speeds. Most noticeable are the pulls between 60 and 130 mph where the 5500+ lbs Range Rover needs it the most.
The RPM is designed for daily driving and comes with RENNtech’s standard 2 year product warranty. Installing the RPM is straightforward and can be done within 2-3 hours by one of RENNtech’s Dealers, or, if mechanically inclined with proper tools the install can be done at home.
The Range Rover sits at the top of the luxury SUV food chain, and with RENNtech’s Power upgrade the Rover inches closer to AMG GLS 63 in performance.
