Dyno tuning question

Hello- recently had my engine -LS3 418 Stroker built by extreme horsepower solutions in Texas. Engine advertised rating based on build specs-575 flywheel HP. Owner Arvil emailed results on dyno 459 RWHP/ 508 RWTRQ. This is on break in oil. 116 HP gap? Can someone enlighten me? Seems like quite a gap I thought theirs only a 30% loss from flywheel to rear wheel? Thank you

Maybe I don't understand your question and I don't mean to be a smart-*** but 30 percent of 575 is around 172.5. Your loss is about 20.1 percent.

Yeah guess my math sucks now I have nothing to complain about LOL! I agree ET counts more then numbers but I just wanted to get what I paid for. I would call him but my sources on this forum tell me he's out of business now. ?? Thanks
