Are there any ECU tunes available to increase power of the 3.0 SC? Generally, blown engines have a lot of untapped power that can be unleashed with the right software. I added huge gains on my '08 535xi with a tune from Cobb. But I haven't seen anything yet for 3.0 SC engine.

 

I'll take one more stab at this. I'd love to pick up an XF but put so many highway miles on my cars for business that I'd really benefit from the good highway gas mileage of the 3.0 SC. However, I need more power than I experienced on my test drive. A good ECU tune should accomplish that, but I'm not finding ANY tuning options for the 3.0. Are there any?

 

The simplest mod would be to fit the LSD from the F Type V6S.

 

There isn't a ton of aftermarket support for the XF. Most will be centered around the 4.2L Supercharged because it has been around so long in various Jaguar vehicles. There is also some support for the new 5.0L supercharged/XFR. The tunes available for those XF models are spendy and the tuners haven't provided much info to back up hp claims.

I wouldn't get into the XF expecting to make it faster with aftermarket mods.

 

What is a LSD?

 

You mean Besides he being on it?

It also stands for Limited Slip Differential..which has nothing to do with the original question.

I have not heard of any ECU tunes yet..the engine and car marriage is still too new.

 

Too funny.

 

What not buy a V8?

I will explain....
The V8 will max 28mpg on the highway and it's got all the punch one would want.

I think the V6SC engine will max 32mpg on the highway. Tune it and you can say goodbye to the extra few miles. It will just drop.

Monetarily, a tune can cost up to $1500. That's probably the difference you will spend on gas over 2-3 year period V6SC vs V8 anyway.
