weirdness in the Throttle Cracker; stalling fix. In tuning on a car ('02 Trans Am) last night I came across
an ugly/weird looking Throttle Cracker Airflow table (see 1st
.gif). I was trying to alleviate a stalling problem that was
seen with throttle blips / braking w/ low throttle.
This is apparently present from stock, it's in my original tunes.
The table just looks wrong; big follower air where you would
think you need none, and zero air added right where you need it
most.
I eyeball-smoothed it (see 2nd .gif) and it seemed to eliminate
the stalling, at least I got a phone call to that effect from the
road on his way home.

what tuning software do you have? 1600 rpm on a stock tune adds 3 g/sec in the 2000's and is a pita lol lowering that is what helps out. let me know what you have to tune with, should be the same in all of them, its the throttle cracker airflow. the one i posted is the one in my car
email me your bin budchevy358@yahoo.com and ill compair it to mine to see where you might beablet to fix it. are you t-rex and full bolt ons only?

Please post your results when you get it straightened out. My RPMs are hanging around 1200 before coming to a stop, so I'd like to see what needs to be changed to make it behave correctly.
