hard start high idle and P0606 LS7

[Tool Guy]

Hi. I am having a little trouble with a 2007 Zo6. The car has a cam, ported heads, and NW 102. The car runs great, but I will get a P0606 (blinking) for a few sec during WOT and P0507. Additionally, most times, the car will need the throttle lightly touched to start while hot, and will idle around 1500-1700 after driving. I smoke tested the engine and don't have any visible air leaks. I tuned the VVE and MAF steady state on a load bearing dyno, and my fuel trims are very close. Did I miss something? The current cam and head package is a revision to a previous setup. I tuned the original setup years ago and never had any problems.

I have attached a tune file and log file at idle.

Thanks
