ECUWEST can now provide a performance ECU remap for your Nissan Navara ST-X 550 And Nissan Pathfinder Ti 550 V6 Turbo Diesel. Check out Justin’s well sorted truck featured here. He had a 3 inch Turbo Back Exhaust and a Stage 2 ECU Tune installed. The thing is now an animal breaking traction easily on the road. One of the best observations is how the hesitation upon take off is now completely gone. Removing the torque limiters within the ECU is key here. We estimate gains to be in the vicinity of a 30% increase in both HP and Torque. Standby for dyno before and after results.
