Alpha Jag Tuning ECU and performance modifications for Jaguars XKR XFR

So we just set a world record while letting go of the gas!!! Fastest XF Supercharged , XFR , XFRS or any XKR 5.0 car while off the gas at the end of quarter mile :) Wow!! #079 He let go of the gas to not go faster because of the fire jacket requirement set at 13sec:). He obviously broke that requirement and had to go home..

In Persuit of Power! ECU programming on Pre 2006 Jaguars cars takes a lot more work for us to get done. For customer not so much, they would just need to remove the ECU and send it in instead of the typical programming through OBD2 port on newer cars.

Custom intake available for 07+ XKR cars. Intake uses oem type of paper filter for best filtration. No sacrifices here! Filter area is about 40% larger compared to stock and flow much more. Increased supercharged whine can be heard with this setup. This system is properly calibrated for proper flow so you will not get any check engine light codes that you get with a lot of the aftermarket intakes.

Lower temperature thermostat is available in combination with cooling fan programming!

New throttle body coming!

We can also install Bluetooth modules and add an aux Input option to your factory radio in 07-09 XKR cars

I decided to create this page to help other fellow Jaguar performance enthusiasts. I have spent nearly two years Dyno developing the ECU tune for my 08 Jaguar XKR 4.2 supercharged. It was a long journey, but well worth the experience. I managed to gain nearly a 100 horsepower out of the car with majority of gains due to the ECU reprogramming. currently have several products available such as ; 1. Prototype intake which use a stock type paper filter elements with 40% larger volume. 2. Also have my own thermostat design which eliminates a major failure point, available in stock or reduced temperatures. 3. Custom ECU tune including Fan duration and turn on temperature modifications 4. Dash programming such as Aux input and many other 5. Music Bluetooth Aux module
