I wouldn't get to worked up about it. You didn't know it had a supercharger on it when it ran the 11.5 so it's not your fault. You just have to realize that car people can look at a list of mods and know what time/speed range the car is capable of and your listed mods do not support 11.5 but with a supercharger they do. No big deal. But I would guess the car is more like 12.4 to 12.7 with the current mods listed. You would also need to know which supercharger and how much boost and if it was intercooled. But it doesn't really matter because it doesn't have a supercharger now so you could probably toss out that time slip. Hope that explains the reactions you got.8)
