About this remap

Saab 9-3 1.9 TTiD 157 bhp Stage 1 — what changes

The Saab 9-3 1.9 TTiD 157 bhp (2002–2012) leaves the factory at 157 BHP and 361 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 1.9 TTiD 157 bhp powertrain (diesel). The result is 238 BHP and 446 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
