24 month warranty, guarantee you do not get anywhere else

For some cars it is necessary (for technical reasons), to completely remove the control unit from the engine. In these cases, we provide 24 months warranty on the engine control unit from the date of chipping. If it is not necessary to remove the control unit and chiptuning is provided without a physical intervention, the warranty covers the performance of the service – chiptuning.

10 year warranty on the software update

We provide warranty to the adjustments made to the software of the control unit for duration of 10 years!
Under this warranty the customer is entitled to:

  • re-upload of the modified software in case it was rewritten to the original by an authorized service

We are insured against possible damage of your car during chipping. Our insurance covers damages up to 1 000 000 CZK. However, it is very unlikely that we could cause any damage during chiptuning the control unit of your car.

The quality of our chiptuning services is supported by a 14-day money-back guaranty. If the customer, within 14 days, finds (on an engine brake) a lower value than we declare, we will charge its car to its original state. In this case, of course, we will reimburse the cost of chiptuning.
