New SAE ratings are 510 and 535 --- 10 up on both ends with the revision.
The motors are super tight, so you will also see a good gain once the car is broken in ( say 4-6,000 miles ). Keep in mind that different Dyno Manufacturers can often show variance among their brands, but I would hang loose for awhile and get the motor broken in before taking it to check.
Keep the rpms under 4,000 for the first 500 miles and a good rule of thumb is to change the oil around 500 miles.
