This MyCal will work with your SHO. The seller should have it unmarried before sending to you, then you have to purchase new tunes from Livernois. If, in the unlikely event your SHO had the same strategy code (you have to have the tuning device in hand to do this, or ask your dealership if you have a good relationship with them), you could purchase the tuner AND tunes from the seller if you worked it out.
