TUNING THE NISSAN RB25DET (R33)

This Nissan RB25DET R33 Skyline GTSt came to FC Tuning for a custom ECU tune. The RB25DET is a proven inline-six turbocharged engine known for strong torque delivery and excellent response to tuning.

We carried out a full FCTuningNistune ECU tune on the dyno, optimising fuelling, boost control, and ignition timing to suit the car’s current specification. The RB25DET responds brilliantly to a carefully dialled-in map.

The result was a smooth, strong power delivery with improved response throughout the rev range. Another well-sorted R33 GTSt leaving FC Tuning with a quality custom tune.
