I am tuning a turbo 4.3 Vortec, I had my VE looking good tuning open loop speed density. I changed my tune to add RRT idle settings, and now everything is running lean. i have a short log of the lean situation, didn't want to drive it.
I've also posted the tune and a log before the tune change. maybe someone can shed some light, maybe I changed something and didn't realize it.

Thanks for the help.

The VE log file was the ok one. there is also a boost run in that one if anybody has any suggestions. It says almost 500 hp, but I know that can't be right, I'm thinking in the 300's.
