D6, D4, D13, D3 & D16 Stage 1 calibration. On-board at your marina across Dorset & the South Coast.
Volvo Penta diesel inboards power cruising yachts, sportsboats and commercial vessels across Poole Harbour and Southampton Water. Factory maps prioritise emissions and longevity over hole shot and mid-range pull. 24Tuning delivers custom Stage 1 ECU remapping for D6, D4, D13, D3 and D16 platforms — mobile to your marina, with diagnostics, factory backup and lifetime software warranty.
Conservative fuelling and torque limiters leave usable performance on the table, especially when planing, towing or running against tide and wind. A Stage 1 remap recalibrates boost, fuelling and torque request maps within safe mechanical limits.
