Solutions
Tuning solutions, explained.
What each solution actually is, the honest pros and cons, and whether it is worth it — plus the legal reality for emissions-related work.
Stage 1
The single most rewarding thing you can do to a modern turbo car. Deeper torque where you actually drive, throttle that finally wakes up, and a calibration that makes the car feel complete — no hardware required.
Stage 2
The next step for a car that has already shed its bottlenecks. Stage 2 reaches further than Stage 1, but it only makes sense once the supporting hardware is in place.
DPF Off
One of the most-searched diesel topics, and one of the most misunderstood. Here is the upside, the downside, and the legal reality — without the spin.
EGR Off
A familiar diesel frustration. Here is what disabling EGR actually achieves — and where the line is drawn legally.
AdBlue Off
SCR faults can be eye-wateringly expensive. Here is what an AdBlue-off involves — and exactly where it is allowed.
Swirl Flaps Off
On some engines, swirl flaps are a question of when, not if. Here is what disabling them in software really means.
NOx Off
A failing NOx sensor can drop a modern diesel into limp mode and start an AdBlue countdown. Here is the honest picture.
OPF/GPF Off
The petrol particulate filter is the gasoline twin of a DPF: same upside, same legal reality. Here it is, straight.
