Running 25% faster through the slowest portion of the track was not solely a mechanical thing resulting from the supercharger removal. You could have gone just as quick through the slowest corner with the blower, so the data is flawed. My guess is that you felt more comfortable in the slow section with less torque, but you can't blame the car for that. I agree power mods are overrated on track, but you can't say that it is slower just because one driver on one track was slower.
Good times though.
