About this remap

Cadillac BLS 2.8T V6 251 bhp Stage 1 — what changes

The Cadillac BLS 2.8T V6 251 bhp (2008–present) leaves the factory at 251 BHP and 350 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 2.8T V6 251 bhp powertrain (petrol). The result is 294 BHP and 404 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
