Went to the dyno

[selbor]

got the car dyno today, the a/f was over 17 after 2000 rpm, made 459hp/480tq, the car fills ok and it does not ping.
I thing the a/f at the dyno is not working properly

Mods are DC intake,3.00 pully,Steeda cat back,JDM chip,bassani mid headers,fluidyne cooler.

Any opinions, thanks.

WAY too lean, if the reading is accurate. I'm surprised it didn't detonate at WOT on the dyno...

That is way lean. If it's correct you're driving a time bomb. I'd confirm with the dyno shop whether your A/F was measured correctly. Better yet, visit another dyno and make sure. If you have a custom tune I'd be surprised if the reported A/F is correct, especially if you haven't experienced any detonation. Good luck. And check it out!
