These numbers show 13-14% loss, on a hot day, a bit too optimistic perhaps.

AMG rates your car at 604 BHP and 738 torques, with a 20% loss to the rear wheel the numbers are 483 BHP and 590.4 torques, 15% loss: 513 BHP and 627.3 torques.

You are getting higher numbers on a hot day, all I am saying is the baseline numbers (before mods) might be a little too high. Dynos vary greatly, but if you test on the same dyno and same ambient temps after your mods, you will know what kind of gains you have achieved.
