The "575 horse tune" is the F-Type SVR tune, the XFR-S tune is 550 PS (542 horse).
The factory 550 PS tune can be put on an XFR, mine has had this done, but it took a long time, a lot of mucking about and several tries, a real learning process in the end.
It can only be done using the proper SDD equipment and a knowledgeable operator, and you need to put an H or X pipe in the exhaust system in place of the front muffler.
As Bigg Will says no dealer will be both willing and able to do it.
As for the factory 575 PS tune, that is "locked" to the F-Type SVR and cannot be put on anything else.
However there are at least three tuning houses I know of which can supply 575 - 600 hp plus tunes for the XFR motor, but you will need not just a tune but a new upper and/or lower SC pulley, check out the F-Type forum, lots of info over there about these tunes & pulleys. That said, I have a suspicion that those tunes will only work for the later versions of the AJ133 SC motor as fitted to the F-Type with the Bosch ECU, and that they won't work on the earlier XFR with the AC Delco ECU. Cambo would probably know.

Well looks like great weather tomorrow sunshine and no rain in the forecast, so I'm gonna run the XFR down the quarter tomorrow morning and see how it does here in utah elevation. It will be a good baseline on stock tune with just the mina intake tube K&N drop ins and catback exhaust. Gotta figure out the best way to launch it on street tires for best 60 ft times. I will post my slips with the results.
[QUOTE=Bigg Will;1666457]The times also show how much power you got left on the table. I had not done the X pipe, or Mina yet on these runs.
I was car 3000, Brian (Kaynite) was car 4000. I won as someone pulled a RED LIGHT..lol
Me Silver, Kaynite Blue. A fun day all around,
Me, Brian (Kaynite) and Patrick (patrickw813)
Man how time flies, almost 2 years ago..lol[/QUOTE
How do you get such low 60 ft times ?
When you launch how do you set up ? Dead pedal ? Feather into it ? Traction control on or off?
I was spinning trying to stomp it I had to figure out a happy medium to get out of the hole decently.
Also you guys run in cali for those slips right?
I did the conversation for altitude and looks like corrected I would be at 12.5
No water burn out, just to clean the tires, just drive around the water pit. Front street tires carry water down the track when you drive through the water pit.
DSC off
Dynamic mode on
power brake to about 1800 rpm
floor it on the last yellow with a sportmans light, if you wait to see the green your slow.
Don't let the clouds fool you, the day we ran it was over 80° and very humid.
I could always get Kaynite on the launch (Yes I've don this before..lol) but he would run me down on the big end.

That's crazy I had horrible 60 ft times every time I launched with DSC OFF I was spinning like crazy I had to launch with it on and only give it half throttle out of the hole to hook up at all . I was in dynamic and sport .

Do you launch in drive or 2nd ?
Launching in drive, DSC kills boost, timing, throttle and will apply the brakes to reign in wheel slip It needs to be off. If you drove through the water box that will kill your traction.

I always drive around the water box and just burn out up to the staging lane to heat em up a bit , I even tried power breaking and really smoking em hoping it would hook up better , but no dice no matter what I tried to do my best runs came by soft launching it instead of full throttle out of the hole maybe it's the tires , a nice set of drag radials might be what's missing .

But too much grip and something expensive is gonna break that your warr is not going to cover..lol. I just kinda roll on the throttle quickly, I've never run slicks on my daily driver to race, taking a big chance if the diff isn't set up for hard launches.
The slips Bigg Will posted we're when I had the Hankooks. Changing to the Bridgestone S-04's allowed me to be more aggressive and still stick.
And it was my first time at the track...ever. So red lighting isn't embarrassing at all. Now it would be.
BTW, Bigg Will, haven't seen any slips from your trip to Irwindale yet. Did you go?
Hey Kay, no the E63 that challenged me backed out Wenesday, not tying to embarrass ya, just reliving a fun day!
Thinking about doing this instead. Street Legal Drags - Auto Club Dragway

That was definitely a fun day. Did a lot of passes and learned at lot. Plus made some new friends!
Let me first apologize for my bad memory, apparently we DO NEED TO LEAVE THE DSC ON!
Vids and commentary from our day a the track Kaynite... https://www.jaguarforums.com/forum/x...oughts-142825/
I was running totally stock too...lol
Yeah that makes more sense, too much power to get out of the hole without spinning like crazy if you turn off DSC, I'm going back to the track next weekend as long as it doesn't rain. Gonna play with it and try to dial in my launch I think there's a couple of tenths I can improve with my current setup.
I'm so tempted to tune it and throw some stickey mickey Thompsons on the back I'm pretty sure at that point I can hit low 12s even at my elevation
