We were recently contacted by Gary in Liskeard who needed urgent help with his Nissan Qashqai. Another tuner had attempted to remap the vehicle, but the job had gone badly wrong — resulting in multiple error codes and an incomplete remap. The car was struggling with poor driveability, severe turbo lag, and performance that was far below par.
When we arrived, we weren’t sure what we’d find. It was possible that the ECU had been left in an unstable or damaged state. At Kernowsport, we’ve seen plenty of cases where poor tuning attempts can create more problems than they solve.
Our first step was to perform a full diagnostic scan and reset all existing data on the ECU. Once we had a clean baseline, we applied a proper Stage 1 performance remap, calibrated specifically for smoother throttle response, improved torque delivery, and more usable power across the rev range.
After finishing the work, we went out on a test drive with Gary — and the results spoke for themselves. He was absolutely delighted, commenting that the remap had completely transformed the way the car drove.
That’s exactly the kind of feedback we love to hear at Kernowsport. It’s why we do what we do — bringing proper, safe, and effective tuning to drivers across Cornwall.
