Home of the Fastest Jaguar F-Type on Record!
Alpha Jag Tuning developed the calibration and performance package behind a 10.6-second quarter-mile Jaguar F-Type, making it the fastest documented Jaguar F-Type on record without nitrous.
The result was achieved through a complete combination of Alpha Jag ECU and TCU tuning, supercharger pulley upgrades, performance intake and supporting modifications, with repeated real-world testing and datalogging used to refine the setup.

Alpha Jag ECU & TCU Tuning • Upper & Lower Supercharger Pulleys • Performance Intake
At Alpha Jag Tuning, we have spent nearly a decade specializing in Jaguar and Range Rover performance tuning, helping owners improve power, acceleration, throttle response, transmission behavior and overall vehicle performance.
We provide custom ECU tuning, ECU remapping and TCU transmission tuning for compatible Jaguar and Range Rover platforms, including F-Type, XK/XKR, XE, XF/XFR, XJ/XJR, F-Pace, Range Rover and Range Rover Sport. Our experience includes the AJ126 3.0L Supercharged V6, AJ133 5.0L Supercharged V8 and AJ34/AJ34S 4.2L V8 platforms.
Alpha Jag also offers proven supporting hardware including upper and lower supercharger pulleys, anti-slip pulley systems, performance intakes, cooling upgrades, lightweight two-piece rotors, lithium batteries and other performance modifications. Each setup can be matched to your exact vehicle, fuel, current modifications and performance goals.
Custom Remote Tuning From Anywhere in the World
Our ECU and TCU tuning is available remotely worldwide. For many supported vehicles, the tuning process can be completed from your phone in your own driveway. Other applications can use our loaner-laptop process, eliminating the need to bring or ship your vehicle to a tuning shop.
We use datalogging and real-world refinement to build calibrations around the actual vehicle rather than relying only on a generic off-the-shelf file. The goal is strong, repeatable performance with good drivability and proper operation of the vehicle as a complete system.
Our approach to tuning goes far beyond simply increasing horsepower. A properly calibrated custom tune can also help improve engine operation, consistency, and long-term reliability by addressing areas where the factory calibration may run unnecessarily lean or overly rich under certain conditions and optimizing the vehicle for the way it is actually being used.
Every Alpha Jag remap is customized to the individual vehicle and build. We use datalogging and real-world feedback to review how your engine and transmission are operating and make calibration changes based on your specific hardware, fuel, driving conditions, and performance goals. Whether your vehicle is completely stock or equipped with pulleys, intake modifications, upgraded cooling, exhaust, or other performance parts, the tune can be tailored around your exact setup.
We can also customize vehicle behavior beyond power output. For example, where supported, Auto Start/Stop can be disabled to eliminate unnecessary engine shutdown and restart cycles, along with other calibration changes based on the owner’s preferences.
The result is not a generic tune downloaded to your car—it is a personalized tuning process developed specifically for your Jaguar or Range Rover, supported by datalogging and continued calibration refinement.
In essence, performance tuning is about more than just numbers; it’s about crafting an unforgettable driving experience.
Whether you’re on the racetrack or navigating winding roads, our goal is to enhance every aspect of these remarkable vehicles.
