RPMs coming down too fast and stalls. Car does not respond to changes?

To fix the stall, I'll need to fix the whole tune... there's no single table which you can adjust to fix this. Just getting the fueling right will take quite a few adjustments (I adjust fueling at the fueling tables rather than just bending the MAF out of shape). I might be able to get it done in a couple of weeks if you can log regularly.

PM me if you want me to tune for you.

In the last weeks I was convinced, begrudgingly, to remove some of the aftermarket components from my vehicle.

I removed the aftermarket performance intake and went back to the stock throttle body. The vehicle now idles smoothly and does not stall. And this is with a virtually stock tune with nothing more than a couple of g/s extra in the desired airflow.

It could have been the xlink but ive heard of many people using them with no problems. maybe the ls3 tb screws stuff up. i don't know. maybe the intake is too hard to tune for. beats me. all I know is that I can drive the vehicle now and it isn't stalling. the motor purrs like a cat at idle.

That's very unusual... but you were lean in the log you posted, so maybe you had an air leak with the performance intake.

Glad to hear that you found the problem.
