Im not saying they are bending the truth. They would probably be able to produce some data to show a car achieved those figures with just the software. They only need 1 to have done it to legally be able to say it's possible.
I have spent (like others on here and some a lot more than me) a considerable amount tuning the 2.0TFSi
I have seen hundreds of cars with different maps go on RR and none have ever made the stated power claim with just a map.
For example when i went REVO stage 1 i was using 100 octane fuel as i lived in Germany and i made 237.3bhp and 278lb/ft
REVO quote 255bhp & 285lb/ft. There was nothing wrong with the car, it was brand new with only 5k miles on the clock as i put 5k miles on it to make sure no build issues etc. I never got anywhere near 255bhp until i did the following
REVO Stage 2
EVOMS
Neuspeed Turbo Outlet Pipe
S3 Intercooler
Autotech HPFP
Relocated DV to K04 position.
Miltek CBE
I then got 257bhp and 302lb/ft.
I have seen one car get 266bhp and 310lb/ft on stage one but that had the same mods i have just listed (as i bought most of them off him when he sold it
) and quite aggressive settings.
You generally get the torque but i have never seen a car get the BHP from JUST a remap.
