That...made no sense (to me).

You're talking about weight, then about grip.

Granted, if she went from 18s to 15s, you could see a diff in launch, but the hps would remain the same. Less weight does not generate hps, to my knowledge. Both dyno methods do not take grip into consideration, hence me calling shenanigans on your theory ().

Course, i could be dead wrong, i'm not a mechanic by any means.
