Hello, have a Golf V with DPF AGR off wich is made from a "TUNER"
On a OBD Gas Tester the Tester says DPF and EGR/AGR are not mounted in this CAR.
But it says Gas test is OK

Is there a way to modifie the ECU MAP that it thinks all is mounted
but Exhaust difference 0mbar is ok and DPF Regeneration will not begin?
AND AGR Rate 0% is OK including the higher Intake 02 Value?

Or exist only the Switch off Method?

ECU is tuned from previous tune from 125HP VMAX OFF to 135HP DPF/AGR OFF
but it feels less Powerfull than before, reaching only 180kph (bevore 199kph)
(Dashs K Value is calibrated via VCDS)
