Golf 7 GTD 2014 rpm not stable, how to diagnose and tune

Problem:
I’ve problem with Golf 7 GTD 2014
Golf 7 GTD 2014 rpm which have not stable I made a diag with original vcds I got only ASAM file not found EV_ECM20TDI01104
2 unknown error

The engine speed is a bit low, I need more power for this car.

Here is the flash I read it using mpps 16.1.02
Vehicle Vin Number: WVWZZZAUZEW012758
VW Hardware Number: 04L906021EE
VW Software Number: 5225
VW System Type: R4 2,0L EDC
VW Engine Code: CRVA
VW System Data: EV_ECM20TDI01104
BTW, I made a mistake I was thinking mpps can read read golf 7 edc17c64.
my mpps is clone one so in the menu have EDC17xx uds that’s why I think it can read it.

The professional advice I got:
Tuning is no good way to “repair” car.
Better to repair your car…and after that using a tuned file…at contrary, you can damage more…please do a log of your car and see where is the problem before..also a good diagnose with good tools…

Problem solved:
It was very simple I made a good diagnosis as advice me.
With original v15.7 vcds
I have not found any of default
I just made an adaptation for the acceleration of idle speed

But the customer still wants to tune his car. I thought the kess v2 will do can read.
And I get professional advice: kess v2 clones not work on golf 7 yet.
CMD CAN Flasher and maybe original ktag 7.008 or magpro x17 will do.
Considering CMD CAN Flasher is cheapest and working, I already got the CMD CAN Flasher when I’ll read the ecu I’ll post the dump here. According to its description, it is packed with only one single USB CAN cable and one CD, and golf 7 is in the vehicle supported list.
