Bring your car in with no check engine lights (EML) or unresolved DTCs. We do a full diagnostics scan before tuning, but:

  • Misfires, lambda sensor faults, boost control issues, or fuelling errors must be fixed beforehand

  • We do offer fault diagnosis, but this needs to be booked separately ahead of time

  • If you’ve got any lights on the dash, it’s best to let us know when booking
