You pay more for Dinan equipment and software because they stand behind their products with a parallel warranty. Parallel, as in "in addition to", not replacement. So let's set the record straight here - Dinan DOES NOT VOID YOUR WARRANTY!
If you purchased a car that was CPO'd the added then Dinan. Dinan will cover the warranty from that point on. I have attached the service bulletin showing that as of 9-1-08 Dinan modified vehicles will not be accepted into the CPO program
