I've suspected my MSP was out of whack for a few months because on two occassions, my tail end lost it during relatively modest accelleration. I probably should have had it checked out because on New Year's Day, the back end really went out - see my "Sooooo Sad" post, above this thread for the pix. I don't think my MSP did anything, although I must admit to panicing and reacting badly during the incident, notwithstanding my two day Master Maserati driving experience in Atlanta. In hindsight, I wonder why the MSP didn't keep me in control.
