Hey im from Australia nd own a 2014 xj6 with full two brothers system and power commander 5
Ive updated firmware and tried a few of the marthys tunes and all I do is highway riding.
Sitting on 100kmh and all im getting to a tank is average 155kms a tank.
(90miles heresay)
I run 98octane fuel ⛽ no other mods besides the two mentioned.
Besides a bung plug for the o2 sensor.

It takes a few tanks of fuel to break the engine in and get the fuel economy up.... I only got 130-160 miles out of my bike new....

the two brothers and power commander will hurt fuel mileage...

How strong are the head winds? That will also affect mileage

Tire pressures?
 
I found myself the same thing.
At first running my Marthy system, it was spraying fuel out the end of the exhaust! -Not quite, but just about
I Re-Mapped my PCV, taking into account (most) Australian fuels dont have ethanol blends in them. (props to Marthy!)
So if you have a PCV, EJK, fuel contoller etc reduce all the values by 10% (10% of their independent value, not reduce by 10).

Another thing I noticed,
I installed the Dbk after a while and running it improved my mileage back to near stock.

Do you have any of these installed or not?
PCV (Power Commander 5), EJK, Juice Box or other fuel controller's
 
What map are you currently running?

Ok found what I was thinking of,
when you posted earlier I knew I had created a thread on the same topic, BUT I was only browsing via my mobile.

Now at home on desktop
Read through this thread it should assist you

Unfortunately I don't have any of my Maps saved from my XJ6S as I had to update my desktop back in July and that info was in an area of unrequired info on the old HD. (as my XJ6S is no more:()

But I believe if you PM members who still have the Maps you would like (hint: read peoples signatures!) they may be willing to share

I think I still have the PCV software on my laptop, if worst comes to worst I can have a fiddle and create a map for you
