If a remapped car develops hesitation, smoke, surging, limp mode or unusual gear changes, bring the symptoms and tuning history for assessment. A software problem is one possibility; a worn turbo, weak injector, boost leak or drivetrain fault can also be involved.
We investigate cars previously tuned elsewhere. Work can include reviewing the installed calibration, comparing requested and actual boost or fuelling, checking torque behaviour and testing the hardware. In some cases the next step is a software correction; in others it is a repair before any further tuning.
A sharper pedal response or stronger low-speed torque does not establish that the calibration works correctly throughout the rev range. Logs and comparable power measurements are more useful than an advertised figure alone.
We welcome customers travelling from Rhondda and across South Wales to our Llandow workshop. Contact us for a free initial consultation with the registration, modifications, fuel, symptoms and previous repair history. We can then agree the diagnostic work needed.
