P1516/P2101 on 2007 Z06

I am tuning a 2007 Z06 with Kooks long tubes, X pipe and a large Cam.
238/240 116lsa. The car runs great and idles great but every once in a blue moon when you let it idle longer than 5 minutes it will set these two codes and dump into reduced power mode. I tried a bunch of stuff but nothing has solved it. Turning off the codes does not help as it still does it but does not show the code. Any ideas would be great.

Thanks

Just somthing I noticed that on a 2006 C6 files I can change the setting on the 2101 but this is not in the 2007 Z06. Can it be added?

Thanks

Check your intake tract ahead of the MAF. There's a felt piece on the bottom side that comes loose regularly on the C6 Z06. Remove it. It's just in there for NVH stuff. You have a cam & Kooks, noise isn't a problem anymore.

The pad is there to obsorb HC's that are released on a hot soak shutdown. So during the Manufactures emissions test, when the whole car is bagged, it doesn't release unburned hc's into the atmosphere, it's called an HC pad.
They come loose and cause problems!

I knew someone knew what that was there for... Thanks Mark!
