Yes is the short answer. Any modification to your vehicle may have an effect on your manufacturers willingness to process a warranty claim. Any part that is modified or affected by a modification may no longer be covered. However, at the same time a remap cannot be used as an excuse to void warranty on non-related items such as suspension of other vehicle electronics. Some will tell you it's undetectable and that you may be able to defraud a manufacturer but as a professional company we are unable to make any such promises to you and any risk of loss of warranty should be carefully considered before modifying a vehicle. As a company we would advise checking with your warranty company before proceeding with any work to see what could be affected.
