Hi - I took the car to a dealer and they compared it to a new car (2019?), It was automatic, so not a manual like mine, but claimed it behaved the same way. So nothing was resolved. My feeling is that this is something that was coded into the drive by wire software of the PCM for some reason. It sucks, but is what it is I suppose. I am really surprised more people have not found this exact same issue. A lot of the other posts seem to be unrelated. This is specifically in other than 1st gear - there is ZERO lag in frst gear. As I sais in y original post, if you feather the trottle and watch the supercharger gauge go towards boost just slightly, and then give it throttle, I don't feel much if any lag. If you just go at a steady speed without any throttle and add throttle - you feel that lag.
