Trust me - it will be REALLY easy to know if the supercharger is not working because the loss of the 100+ horsepower it provides will be VERY noticeable! So if the SRT feels like your N/A, then the SC is not working, but if it wants to break the tires loose in first and second gear and/or slams you back in the seat when you floor it at 65 MPH, then you know it's working...LOL!
