About this remap
Audi A4 3.0 TDI 245 hp Stage 1 — what changes
The Audi A4 3.0 TDI 245 hp (2008–) leaves the factory at 245 BHP and 500 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 3.0 TDI 245 hp powertrain (diesel). The result is 300 BHP and 620 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
