The calibration is the start of how you look after the car, not a reason to leave it alone. Most of what matters afterwards is ordinary maintenance, done a bit sooner.
Use the car gently until it is warm. That was true before the remap. It matters more when the engine is making more torque from lower speed. Short, cold trips are hard on a diesel particulate filter whether the car is tuned or not. If your driving is all urban, say so before we calibrate it. We would rather set the car up for how it is used than chase a number you will never hold.
Oil, and the parts that wear
More torque means more load on the oil, the turbo and the clutch. Shorten the oil interval rather than stretching the one in the book. Use the grade the engine was specified for. A tuned car does not need a secret oil. It needs clean oil, on time. Induction hoses and charge pipes see more pressure. If one was already soft, it will be the part that splits.
High mileage does not automatically rule a car out. A van that needs torque for work can still be a sensible Stage 1 at well over 100,000 miles, if the turbo and the clutch are honest. A performance car that is driven hard, on a tired turbo, is a different risk. We will diagnose a fault. We do not warranty parts that were already worn, and we do not pretend a remap stops wear.
If it is not right
Bring the car back. If the calibration itself is causing a running problem on a Stage 1 or Stage 1+ car, we will assess it. Do not add another file from somewhere else on top and then ask us to explain the result. Tell us what it is doing, and whether anything else has been fitted or coded since the visit.
The guarantee wording, including what Stage 2 and hardware builds do and do not cover, is on the remapping page. If you have not booked yet, check the car first.
