I checked my Dinan receipts. I have stage 4 engine and transmission software that matches up with Dinan other mods other than the S/C. There is engine software that comes with the supercharger but there is no stage associated. Stage 4 is to match up with Dinan throttle body, air flow meter, cold air box and exhaust.
