how do I reduce engine load or airflow when slowing down to a stop?

I have an 01 silverado 5.3 with headers and a mild cam. Just wondering what table I need to adjust to let the idle drop down more when slowing down like coming up to a stop sign or something. It acts kinda like it's adding airflow to the point you can feel the transmision downshifting when rolling up to a stop. once I'm almost stopped the idle drops to normal. Just need to reduce the airflow a little when off the throttle slowing down, Would that be the throttle cracker or the follower? I get those two confused. Thanks in advance.

B4309 take 20% out of 0-32 MPH and 400-2200 . Select all that and take out 20% at first and then maybe another 10% you can zero it, but down low like driving in a parking lot takes a little more effort.

Throttle cracker is based off Speed
Throttle follow is based off throttle.

Change B4311 to 25mph and B4312 to 22mph and see how that does.

If your B4307 has too high of numbers it will do what your seeing as well.


Post your tune and a datalog including throttle cracker and throttle follower as well as IAC position.
