What each modification does

Stage 1 for Mercedes-Benz CLS 450 (367 hp): Software-only remap for a car with standard hardware. 367 hp to 417 hp and 500 Nm to 614 Nm.
Stage 2 BASE for Mercedes-Benz CLS 450 (367 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. 367 hp to 427 hp and 500 Nm to 633 Nm.
Flex fuel mod for E85 or other fuel types for Mercedes-Benz CLS 450 (367 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 Mercedes-Benz CLS 450 (367 hp): Faster shift times, modified shift points, raised torque limiters, raised rpm limits and higher clutch pressure where needed.
Pops and bangs for Mercedes-Benz CLS 450 (367 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 Mercedes-Benz CLS 450 (367 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 Mercedes-Benz CLS 450 (367 hp): The electronic speed limiter is removed, raised or lowered.
DTC off for Mercedes-Benz CLS 450 (367 hp): Selected fault codes are switched off so they are no longer stored or shown.
Start/Stop System Off for Mercedes-Benz CLS 450 (367 hp): Start-stop is switched off by default.
Cold start off - Catalyst heating off for Mercedes-Benz CLS 450 (367 hp): The catalyst-heating phase after a cold start (raised idle, retarded ignition) is removed.
Exhaust flap control/off for Mercedes-Benz CLS 450 (367 hp): Exhaust valves can be opened or closed independent of the driving mode. For cars with valves in the original exhaust.
Catalyst off for Mercedes-Benz CLS 450 (367 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 Mercedes-Benz CLS 450 (367 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 Mercedes-Benz CLS 450 (367 hp): Monitoring of the fuel vapour (EVAP) system is switched off.
AGS off for Mercedes-Benz CLS 450 (367 hp): The active grille shutters are switched off in software.
Torque monitoring off for Mercedes-Benz CLS 450 (367 hp): Torque monitoring is relaxed so a higher torque does not trigger limp mode.
Readiness ok for Mercedes-Benz CLS 450 (367 hp): Readiness monitors are set so the car reports ready at an emission inspection.
Checksum Correction for Mercedes-Benz CLS 450 (367 hp): The checksums of the file are recalculated so the control unit accepts the modified software.
