About this remap

Buick Excelle 1.6 T 180 hp Stage 1 — what changes

The Buick Excelle 1.6 T 180 hp (2003–) leaves the factory at 180 BHP and 235 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 1.6 T 180 hp powertrain (petrol). The result is 210 BHP and 300 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
