The higher dyno numbers are due to the final drive ....short gears dyno lower...
Look at mmandff ...when they go from say a 3.31 to 4.10 they usually lose 20-30 whp (when dynoed in the same 1.00 gear)...

So you have it :
Zl1 final drive: 3.73
2013 gt50: 3.31

Primary gears are also longer on the gt500...so
