What each stage needs

Stage	Power	Torque	Hardware
Standard	154 bhp	343 Nm	None
Stage 1	185 bhp	400 Nm	Software only

Risk on this engine: low

Significant 20% gain: boost and fuelling pushed beyond factory settings.
Diesel: no knock risk. Primary risks are EGT, turbo health, and injector wear.

How to keep the risk down

Check intercooler efficiency before tuning.
Monitor EGT under hard driving: sustained temps above 700 C accelerate turbo wear.
DPF (if fitted) will accumulate soot faster: ensure it is in good condition.
Keep a copy of the original ECU file before flashing.
