About this remap
Audi Q7 4.2 TDI 340 hp Stage 1 — what changes
The Audi Q7 4.2 TDI 340 hp (2006–) leaves the factory at 340 BHP and 760 Nm of torque. Manufacturers deliberately detune this engine to separate it from more expensive variants in the range — a Regal Tuning Stage 1 calibration safely recovers that headroom through the ECU alone: no hardware changes, no dyno risk, fully reversible.
Fuelling, boost pressure, ignition and torque limiters are optimised within the safe tolerances of the 4.2 TDI 340 hp powertrain (diesel). The result is 390 BHP and 900 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
