Recently had a dyno day at a local shop.
they had an older guy pull up in a 2009 ZR1 (clean car) to do a couple pulls.
His car ended up with 626 rwhp can't remember torque numbers.
He wouldn't talk about his car though.

Just curious what mods might be done for him to get those numbers?

I won most hp overall,so maybe that's why he wouldn't talk to me.
