No, it does NOT void your warranty. That's a ridiculous assumption - and would certainly not explain how I have had Dinan on both new and CPO cars and never had any issues with warranty, including the extended CPO warranty that goes beyond the 4/50 factory warranty. 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!
