Default Looking to tune my XFR

I’m located near Chicago Illinois and finally looking to tune the kitty. I finally installed the Mina supercharger pulley yesterday. That completes the axel back exhaust, intake tube, drop in kn&n’s and the pulley upgrades.

Any suggestions would be great.

I am over in Aurora/naperville and I already have the eurocharged handheld programmer. You should be able to contact them on this forum or directly and arrange to just pay for the tune since you won't be needing the hardware.

Really appreciate the offer, thanks!! I was just looking at their handheld and they claim that once it’s used it locks to the vin#. At least now I have someone to go to, thanks!

Are you happy with the tune from them? They claim to increase the BHP from 509 to only 536 on the site. Seems rather low.

Did they actually dyno the car or just a flash after the base upload?

If you look at the F-Type and XE forums, VelocityAP gets the most love amongst all the tuners. There are several forum members that posted dyno results and you can find figures on their website as well. Tune and pulley combo, they claim 600+ hp.

Right, I am currently talking things over with them. I just don’t know how to feel about a flash tune vs a true dyno tune. It feels rather artificial. Or is it just how it is these days?

Yep, it's pretty much how it is these days on the Jag AJ133SC and AJ126 engines.
Very rarely will a dyno tune give you a better result than a modern flash tune on these engines, and good tuners like VAP have spent a lot of time, effort and R&D getting their flash tunes "right". VAP are also happy to talk to you about minor tweaks to one of their flash tunes to create a custom tune for you.
One of the advantages of a VAP tune is you can flash it back to stock any time you like in the comfort of your own garage, which is not something you can do with a dyno tune.
From a very happy VAP customer!

you would need a custom tune for custom mods like bigger injectors or higher fuel pressure ECT.
its how it is to a point now.
its called a canned tune . but if all is the same on the car the tune originated (most definitely dyno'd) as the mods on your car, there will be very little difference in dyno results . and little need to re dyno the same tune on practically the same car .
there is a big difference between a chip tune (irreversible) and a flash tune .
again talk to Cambo . he has tuned the quickest recorded 1/4 mile 4.2 xkr and the quickest 5.0 xkr in the WORLD.

Old Jaguar doesn’t tune the 2013+ models as they have the Bosch ECU vs the Denso. They referred me to VAP, and so VAP it is!

I cannot do a remote tune on the Bosch PCM, there are several Bosch cars here in Sydney that we have put tunes in, but doing it on the other side of the world, it's a problem...

There is a certain 5.0L Range Rover Sport here in Sydney that just walks away from my XKR... scary fast... it's a Bosch car.

No worries. I appreciate the reply.

Default 2012 XF vs. 2012XFR for parts swap

New to the forum but a great asset

I currently own a 2012 XF and damage my front end. I found a 2012 XFR hood and want to swap. Does anyone have thoughts about using the XFR parts on a XF model? I am think of getting more XFR parts to help my XF??

Also any suggestions to bring my XF up to max speed and driving control?

Thank You
Doug
