I have tried a few tunes, I got this one to where it felt good all over, I was even able to liven up lower rpm/speed pulls by what felt like a lot, however, suddenly now I am getting a maxed lean condition when I am coasting or going a steady speed and not applying the throttle. If I just touch the throttle it goes away and I have been chasing it for two days.
This is a bone stock 2007 Trailblazer SS w/a hiflow air filter and air box mod only.
The number looked good and it felt great except this lean issue that threw DTC.
Any help is much appreciated!

Again, any help is greatly appreciated. I thought it was in the DFCO, but if it is, I'm just missing something.
