What each modification does

Stage 1 for Audi A8 55 TFSI (3.0T) (340 hp): Software-only remap for a car with standard hardware. 340 hp to 401 hp and 500 Nm to 651 Nm.
Stage 2 BASE for Audi A8 55 TFSI (3.0T) (340 hp): Remap matched to hardware upgrades. Which parts are needed differs per engine. If needed we fine-tune the file up to 3 times free of charge, based on the datalogs you send us. 340 hp to 422 hp and 500 Nm to 682 Nm.
Stage 3 BASE for Audi A8 55 TFSI (3.0T) (340 hp): Remap for a larger or hybrid turbo with supporting hardware. If needed we fine-tune the file up to 3 times free of charge, based on the datalogs you send us.
E85 or other special fuels modification for Audi A8 55 TFSI (3.0T) (340 hp): The calibration is set up for one special fuel, for example E85. This is not a flex-fuel setup.
Flex fuel mod for E85 or other fuel types for Audi A8 55 TFSI (3.0T) (340 hp): The engine adapts to the fuel that is in the tank, from petrol to E85 and any blend in between. This is not a fixed E85 calibration.
Gearbox TCU tuning for Audi A8 55 TFSI (3.0T) (340 hp): Faster shift times, modified shift points, raised torque limiters, raised rpm limits and higher clutch pressure where needed.
Pops and bangs for Audi A8 55 TFSI (3.0T) (340 hp): Fuel still injected on overrun ignites in the exhaust and gives the crackle sound. Intensity can be set: soft (burbles), normal, hard or flames.
Hardcut limiter for Audi A8 55 TFSI (3.0T) (340 hp): Ignition is cut at the limiter instead of fuel being reduced early, so full power is available to the redline.
VMAX speedlimit on/off higher/lower for Audi A8 55 TFSI (3.0T) (340 hp): The electronic speed limiter is removed, raised or lowered.
DTC off for Audi A8 55 TFSI (3.0T) (340 hp): Selected fault codes are switched off so they are no longer stored or shown.
Start/Stop System Off for Audi A8 55 TFSI (3.0T) (340 hp): Start-stop is switched off by default.
Cold start off - Catalyst heating off for Audi A8 55 TFSI (3.0T) (340 hp): The catalyst-heating phase after a cold start (raised idle, retarded ignition) is removed.
Exhaust flap control/off for Audi A8 55 TFSI (3.0T) (340 hp): Exhaust valves can be opened or closed independent of the driving mode. For cars with valves in the original exhaust.
Catalyst off for Audi A8 55 TFSI (3.0T) (340 hp): Catalyst monitoring by the lambda (O2) sensor is switched off so a sport catalyst or decat does not raise fault codes.
DPF/OPF/GPF off for Audi A8 55 TFSI (3.0T) (340 hp): The particulate filter function (diesel DPF, petrol OPF/GPF) is switched off in software. The filter has to be removed physically first.
EVAP off for Audi A8 55 TFSI (3.0T) (340 hp): Monitoring of the fuel vapour (EVAP) system is switched off.
SAI off for Audi A8 55 TFSI (3.0T) (340 hp): The secondary air injection system is switched off in software.
AGS off for Audi A8 55 TFSI (3.0T) (340 hp): The active grille shutters are switched off in software.
Cylinder On Demand off for Audi A8 55 TFSI (3.0T) (340 hp): Cylinder deactivation is switched off so the engine always runs on all cylinders.
Torque monitoring off for Audi A8 55 TFSI (3.0T) (340 hp): Torque monitoring is relaxed so a higher torque does not trigger limp mode.
Readiness ok for Audi A8 55 TFSI (3.0T) (340 hp): Readiness monitors are set so the car reports ready at an emission inspection.
Boost Sensor Calibration for Audi A8 55 TFSI (3.0T) (340 hp): Calibration for an uprated boost pressure (MAP) sensor.
RPM Limit Mod for Audi A8 55 TFSI (3.0T) (340 hp): The engine speed limit is raised or lowered.
IMMO_OFF for Audi A8 55 TFSI (3.0T) (340 hp): The immobiliser check is removed from the ECU, so the engine starts without the immobiliser.
Checksum Correction for Audi A8 55 TFSI (3.0T) (340 hp): The checksums of the file are recalculated so the control unit accepts the modified software.
