I'm no expert on C6 Z06 whp and wtq, but your whp dyno represents an 11% parastic loss of hp through the drivetrain (% of bhp lost in whp dyno). Parasitic losses of up to 15% in rwd cars are not unusual.
Of course as I say, I don't know how other C6 Z06 stock cars dyno, but I'm sure others will who know will weigh in.
I pulled 370.5 rwhp on my bone stock C6 MN6. 07 Z06 with intake and catback pulled 440 rwhp on the same dyno, but it was running rich. He was running ~ 10 to 1 where I was ~ 12 to 1. After a tune he pulled 475. You really need to check your AFR.

I'll bet you and Oldmansan are talking about the same Z06 from CMS Dynoday.
I have no plans to tune my car, so my A/F isn't of concern. I was just curious of my power numbers stock.
I'm not sure if all the Z06s run rich from the factory so I was just relaying information. The numbers I put down and the Z06 put down were not on a DynoJet, so I can't intelligently comment on whether your numbers are normal or not.
I wasn't trying to steer you towards a tune, but the Z06 owner told me emphatically before his dyno run he wasn't going to tune his Z06. That changed quickly when he saw how rich it was running and his dyno numbers relative to other cars.

So long old GAL, it was great running with you!!!!!!!!
Sound like it real close - with a little tuning it'll wake right up and get up in the high 470's in the RWHP!
I've heard of others pulling higher but it might of been from the tune or just a better day and of course a different Dyno - You should be happy becuase it is a great baseline to build off of

How are my stock LS7 dyno numbers?
As long as it didn't dyno ridiculously low, I'm cool with that.
