What each modification does

Pops and bangs for Audi A6 4.2 FSi V8 (335 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 A6 4.2 FSi V8 (335 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 A6 4.2 FSi V8 (335 hp): The electronic speed limiter is removed, raised or lowered.
DTC off for Audi A6 4.2 FSi V8 (335 hp): Selected fault codes are switched off so they are no longer stored or shown.

Catalyst off for Audi A6 4.2 FSi V8 (335 hp): Catalyst monitoring by the lambda (O2) sensor is switched off so a sport catalyst or decat does not raise fault codes.

Idle RPM Mod for Audi A6 4.2 FSi V8 (335 hp): The idle speed is raised or lowered; the rev limit can be changed as well.
