Strange Dyno reading PLEASE HELP
 

Hello everyone,
I was a happy owner of 3.0 A6 until I took it for a dyno test...
There are no fault codes, dpf and egr still present, no smoke etc.
I am hoping someone can be able to pinpoint me in the right direction as what is wrong with my car/map.
Thanks

Oh btw the car has been remapped by Quantum Tunning suppose to 300 bhp and 600 Nm ...but there was no Dyno to confirm.
That's not even kinda close...
