The programming "sucks" because Chrysler doesn't want the car coming in on a rollback, owner complaining he broke the differential "driving normally" instead of sidestepping it at 7 grand...on slicks at the track.

But potential warranty claims really don't apply here since the OP's warranty was void the first time he raced it.... so he might as well have given it a "stock" tuneup at the same time. Race it once, presto...no more warranty!
