They claim "Stunning results" Anyone have experience with their ECU remapping? Seems it's plug and play for the 2007 XK but not the 2008 on?
Jaguar XK Performance ECU Tuning 2007-Up

 

There are plenty of postings about ETG's tune. I am having a remap done by Eurocharged this week. So be on the lookout for the results. I am having a before and after dyno done.

 

Here's the thread:

I did the pulley and tune on my 2010 XKR and I love it, the dealer doesn't seem to know its there, and I have had no problems with it.

 

If it were more like $500, I would consider it. That's a lot of money other wise.

Can the upgrade be removed and re-sold to someone else at a future time?

 

Did you dyno before/after?

 

I've done Eurotoys tuning about 2.5 years ago on my 2008 XKR. Def felt a different in the SOTP but didn't do before and after dyno though. Eurotoys uses Viezu tuning which is a UK tuning company: Jaguar XKR tuning

With all my mods, I've gain a "rough" estimate gains of 84RWHP and 77RWTQ. Unfortunately, I did not do a baseline on my car but these estimate gains are based on Gn4hir's stock dyno run. Heat soak was the major problem and robbed power. I might have gained more if not for the dyno shop being an hour away.

 

The EuroCharged tune is done and the results are in. I will post the Dyno charts later. I have a few questions about the chart results before I post them. The bottom line is an 18.8% increase in rwhp which is very respectful!

Before - The best dyno run on my stock 2010 XKR (510bhp) produced 382 rwhp and 349 of torque.

After - the best dyno run after the tune and pulley install produced 454 rwhp and 408 of torque.

For $1,075 that included the tune, pulley and the two dyno runs - I believe a gain of 72 rwhp is a "best" value win.

Unfortunately, I have not had a chance to take the monster out because its been raining here constantly for two days - I will post the dyno charts once I've had a little more consulting about the charts and more real world driving comments after this weekend.
