Hi Guys,

I posted in this forum a little while back with some of our XF-R Tuning options, but forum member boiler read my post in the XJ forum: https://www.jaguarforums.com/forum/x...7/#post1143170 and suggested I post some more info here:

ECU Tuning:
Jaguar/Landrover 5.0 ECU Tune
For the XF models, we offer an MPF flashing tool which runs off Android platform software. You download an app to a Smartphone or tablet, and use the MPF cable to read the original file from your car. The app automatically uploads the original file to our database, notifying our file writing team. Once they have custom-written the file for your specific vehicle, they upload your modified file and the app notifies you it is complete. Plug into the OBD port and you can upload the MOD file to the car.

The main advantage of this system is that you retain the tool and can switch back to the original file at any time.

For the tune + MPF Tool is $837 + Shipping (it is pretty small, ships inexpensively.)

All our tunes include $3.5 million in insurance coverage on your engine.

We are able to tune all modern Jaguar/Land Rover engines using this technology, including diesels.


Pulley + Tune:
Jaguar/Landrover 5.0 Supercharger Pulley + ECU Tune
We also offer the same tuning package with the addition of a pulley for $995. The pulley/tune package is available for both 5.0 & 3.0SC engines.

We have both the pulleys and MPF tools in stock for immediate shipment. If anyone is interested we'll offer a $100 rebate to any customers who produce independent dyno data. Always think it looks better coming from other owners

 

Im very interested in the tube for the XF-R. What kinds of performance gains are we to expect from it?

 

Never dyno-ed it with just the tune. We did a 5.0SC XKR once that the customer dyno-ed and he made 605BHP! I usually expect the pulley & tune to make around 50BHP, so I would expect to see 20-25BHP, conservatively.
