4. When we receive your old chiptuning set, we will process it within 3 days and then return it to the address you supplied when ordering the upgrade.

As one of the largest chiptuning suppliers in North Europe, we wish to continue giving you great service also in the future!

( Sometimes we can not use your old used box for your new car - in these cases we may take the liberty of using another pre-owned box of equal quality - if we have in stock - for your upgrade. )
