Our Services for Toyota

Toyota's turbocharged engines — from the GR Yaris's G16E-GTS three-cylinder to the D-4D diesel range — carry conservative factory calibrations that leave real headroom. Our Stage 1 remap for the Hilux 2.8 D-4D adds approximately 35bhp and 80Nm of torque, transforming towing capability, while the 2.0 D-4D in the RAV4 and Corolla gains noticeably sharper acceleration.

The GR Yaris's 1.6-litre three-cylinder turbo is a rally-bred engine with enormous tuning potential — our calibrations lift it from 261bhp to over 300bhp through revised boost targets, fueling, and ignition timing. The GR Supra's BMW-sourced B58 inline-six gains 40-60bhp, delivering genuine sports car performance that matches its stunning looks.

Toyota's D-4D diesel engines power the Hilux, Land Cruiser, and older Corolla/Avensis models. Our economy calibrations optimise injection events and turbo spool behaviour for cruise efficiency, helping fleet operators and farmers achieve 10-15% better fuel economy without any loss of low-end pulling power.

Toyota D-4D vehicles — especially the Hilux and Land Cruiser used in stop-start agricultural and construction work — are prone to DPF clogging from incomplete regeneration cycles. We diagnose whether the issue is soot loading, sensor failure, or injector problems, and provide the correct software solution to restore normal operation and prevent recurrence.
