Help! Motor dying when revving past 3k

Hi guys.
I have an '09 1198s with 30k miles.

Bike fitted with a PC V + autotune.
Over a month, bike map started putting extra fuel on the map, to the point of hitting my +30% cap.

Then one morning bike just dies when revving past 3k / 4k.
It is as if the bike is not getting any fuel.

So, unplugged PCV, fitted a new fuel filter.
Also swapped the VR and swapped ECU's, and still no luck.

Any ideas very welcomed...

Cheers,
Nuno

Further info:
Spark plugs checked
Battery, alternator & ground checked
Sidestand previously disabled

Injectors are working, accelerating 1st increases shower and the decreases (remember, ECU is ok)

Any gurus here like to share some wisdom as to what is causing this?
Help desperately needed...

PCV shows TPS is working, but so far seems the likeliest candidate

The best person to ask would be Mark at Ducshop. I havent heard of this issue before and he might have some good insight on it.

Guys
The TPS and VR were to blame.
Hope this helps someone else down the line
