By reprogramming the ECU, not only were we able to increase power for the Jaguar 5.0 Supercharged engines, we were also able to remove the speed limiter, hesitation/flat spots, and raise the RPM all while improving fuel economy by 10-15%.

We can take the 470hp 424lbs tq XF Supercharged and 510hp 461tq XFR Supercharged to: 565hp & 525+lbs tq with just an ECU tune. By replacing the supercharger pulley, total gains of 590hp & 550+lbs tq can be obtained.

For owners who are not accessible to any of our dealers, you are in luck. We are offering a new package where you will be able to reprogram your vehicle through the OBD II port in the comfort of your own home. The process is simple, safe, and easy. Contact us directly for more information.

Please inquire about any Jaguar model.

Contact the sales department for any questions or concerns.

Please obey all traffic laws. ECU Tuning Group does no encourage speeding.

 

Please view the original post. Gains have been updated to 565hp 525+lbs tq with an ECU tune and 590hp 550+lbs tq with a pulley and tune.

We posted new information about the Jaguar 5.0L Supercharged in our blog.

 

So what your are saying is that there is 0 difference in power delivery for the 2010/2011 XF Supercharged and the XFR with your tune? They bot hwill make the same power with your tune/Pulley?

Also, do you offer a pulley with your tunes? If so, is it a 2.5 psi boost increase or different?

I currently have a 09 XF Supercharged and also would like to know what you offer for it?
I am shopping for a XFR now but if the 10/11 XF Supercharged will make the same I should save the $ I would dump on a XFR?

 

They offer a tune and pulley upgrade for the 4.2sc acording to the link in his second post. But I looked at their website and didnt see what increase you would expect.

 

+25/24 w/o pully. +55/65 with

Correct, tuning a XFR and XF Supercharge will result in the same power tuned, with or without a pulley. The supercharger pulley is a 1.5lbs pulley.

Details for your 4.2L XF Supercharged can be found here.

If you're main concern is about power, the XF Supercharged with a tune will suit you just fine. On the other hand, if you want power with the added bits of luxury, get your hands on the XFR. It's really all about personal preference. Which ever one you pick up, they're both beautiful cars.

 

My last questions are : Can I load the ROM myself through the OBD and also FLash it back to stock at any time myself? Kinda like for warranty issues or if I sold the car ,things like that? Can it be detected like GM can see on the ZR1/ CTS/ETC if it was flashed back to stock?

And what are the effects if I added a MINA Gallery exhaust? Would the tune still be on target or do you have a secondary tune in place for that? Axle back or full Catback with Xpipe and no resonators. I assume even with a tune K&N filters or some intake mods would still be not ideal due to the sensitivity of the dual MAF's?
Other than that this is a real good route for me and others in the very near future!

 

Hi. I am also interested in the procedure to install via OBD from home in a 2011 XFR as I am in NZ.

In your testing did you manage to eliminate the backfiring these cars seem to have?

Thanks.

 

Will it still pass California smog testing?

 

ETG,
"Correct, tuning a XFR and XF Supercharge will result in the same power tuned, with or without a pulley. The supercharger pulley is a 1.5lbs pulley"

I'm curious. I thought the XFR already comes with a different pulley than the SC, to account for the extra 40hp. You are sying the hardware is exactly identical, and the XFR has just a higher state of tuning coming from the factory?

Yes, that is what he's saying - "Through the months of testing and data logging, we noticed that there are absolutely no internal differences, other than exhaust (XKR-S), between the 470hp, 510hp, and 550hp Jaguars."

The software is completely undetectable to factory diagnostics. All your scheduled maintenance and warranty work shall be carried out just the same as before. If you wanted to reflash your car back to stock, your closest ETG dealer is 212 Motoring in New York.

Additional modifications such as Mina Gallery exhaust or K&N intake...we have had no prior experience with Mina Gallery's products. We always recommend using Quicksilver who work hand in hand with the Aston Martin and Jaguar British Race Team. Through the years, we have noticed K&N loading up their filters with oil which in return restricts airflow. To get rid of the excess oil, we always recommend our customers to soak the filter in warm water and let air dry.

 

100%. You will not have any issues whatsoever.

BMC air filters do not list any available filters for the 5 liter engines....

 

Thats strange. I guess I was checking their site for the 4.2 instead of 5.0 and accidentally got confused. Thanks for letting me know. I edited the #13 post

 

ETG,
Can you provide a link to the dyno sheet for the 2011 xf 5.0L S/C -Thanks

Is there anything you can do for Jaguar S type R's? Most of us would love a small, reliable bump in HP and TQ, but above anything would like our cars to redline before 4th gear. Please come over to the S-Type Forums and we'll entertain you.
