About this remap
Ferrari 512TR 4.9 V12 48v 428 hp Stage 1 — what changes
The Ferrari 512TR 4.9 V12 48v 428 hp (1991–) leaves the factory at 428 BHP and 491 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 4.9 V12 48v 428 hp powertrain (petrol). The result is 447 BHP and 510 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
