Can't get the idle right after adding the NW102 TB, please help! (tune file attached)

[Kamaro]

My car was idling before that, but when I installed a NW102 TB and changing the ETC Area Scalar to 7155 (calculated based on the new area), the car would idle OK (at about 900 rpm), but when I blip the throttle it would go down low too much and starts hunting, and sometimes it will die on me. my car is a manual so sometimes it will hunt and die during coasting or when down shifting at slow speeds. Can someone please take alook at my tune file and suggest me any fix??

Thanks...

Post log also.

Here you go. You'll notice how the rpm will start hunting up and down as soon as I start the car, and it dies when I tried to move it. Its so annoying that I need to rise the rpm 2000 rpm or more just to start moving the car!

Is there a reason you have it in open loop and no wideband reading?

throttle follower and final min would be some more places to look, not to mention spark and adaptive idle...

I have no idea about that. I'm using the GM LS controller kit which already have two O2 sensors and they are connected. If you mean an external/stand alone Wideband sensor, then no, I don't have it in this car.

please note that I have no idea about tuning in an engine with HP Tuners, I hardly can change values and write in the tune to the ECU!
