What each modification does

Stage 1 for Audi A4 S4 4.2 V8 (344 hp): Software-only remap for a car with standard hardware. 344 hp to 368 hp and 410 Nm to 433 Nm.
Stage 2 BASE for Audi A4 S4 4.2 V8 (344 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. 344 hp to 375 hp and 410 Nm to 440 Nm.
E85 or other special fuels modification for Audi A4 S4 4.2 V8 (344 hp): The calibration is set up for one special fuel, for example E85. This is not a flex-fuel setup.
Pops and bangs for Audi A4 S4 4.2 V8 (344 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 A4 S4 4.2 V8 (344 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 A4 S4 4.2 V8 (344 hp): The electronic speed limiter is removed, raised or lowered.
DTC off for Audi A4 S4 4.2 V8 (344 hp): Selected fault codes are switched off so they are no longer stored or shown.
Cold start off - Catalyst heating off for Audi A4 S4 4.2 V8 (344 hp): The catalyst-heating phase after a cold start (raised idle, retarded ignition) is removed.
Exhaust flap control/off for Audi A4 S4 4.2 V8 (344 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 A4 S4 4.2 V8 (344 hp): Catalyst monitoring by the lambda (O2) sensor is switched off so a sport catalyst or decat does not raise fault codes.
EVAP off for Audi A4 S4 4.2 V8 (344 hp): Monitoring of the fuel vapour (EVAP) system is switched off.
SAI off for Audi A4 S4 4.2 V8 (344 hp): The secondary air injection system is switched off in software.
IMMO_OFF for Audi A4 S4 4.2 V8 (344 hp): The immobiliser check is removed from the ECU, so the engine starts without the immobiliser.
Anti lag for Audi A4 S4 4.2 V8 (344 hp): Boost is kept up when you lift off the throttle, so the turbo responds sooner when you accelerate again.
