Logs and tune files are the best way to get help.
Need to see what's going on.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
here s my tune i will post a log tomorrow.
i appreciate the help
If you really want it to go down fast you can try turning CFCO back on
Post a log when you get a chance.

here it is looks like it only does it at low rpms.
appreciate the help.
I would recommend focusing on idle proportional and integral... This looks like an airflow issue - pulls timing, but throttle closes slow... Just an observation...

I think so too. I've just been able to make RPM's fall super fast on mine with CFCO on (too fast probably), so figured that was an easy thing to try

ill tried the CFCO BACK on if not ill try to teak the idle proportional and integral.
thanks i let you guys know what does the trick.
no luck by turning back on CFCO
Ah well it was worth a shot
In that case you're back to Greg's idea
what throttle body you have?

102lsxr intake and a ls7 ported tb.
could try the "idle" "rpm" "follower" tables for decr steps if u lower those numbers i believe it makes it faster go to lower revs less amount of steps to get back to idle, from 1600rpm one table (coast decr in drive) u have at 40 steps could try halving that see if it helps in those tables the others look ok
Before adjusting the proportional and integral tables - try putting 5650 in the etc scaler then try this base running airflow table... This is fairly common with prochargers due to how much air they keep pushing... You really need a torque throttle follower table, but your ecm doesn't have that built into it... I just know from how little min air your running, it should be much less with rpms... You'll still mose likely have to adjust your idle airflow tables, but see how this does first...

You'll also need to adjust your dfco settings, getting this back to working will help a lot too...
