Suzuki SX4 S-Cross 1.4 Boosterjet Stage 1 Remap
On Suzuki SX4 S-Cross 1.4 Boosterjet turbo petrol engines a Stage 1 remap recalibrates the boost pressure, ignition timing, fuelling and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.
It depends on the generation and the stock output. 1.4 Boosterjet engines with 129–140 bhp reach 155 bhp with a Stage 1 remap; the largest gain is +26 bhp (1.4 BoosterJet 129hp). Pick your version in the table below.
