I think a 15% reduction is overly optimistic for most. The side pipes are lossy... and the rear end CAN be... IRS vs. solid axle... all depends on the setup...
You have about a 25% loss which seems a little high, 20% is the rule of thumb I've read elsewhere, maybe something going on with your driveline.
