stalls after highway cruising - Easy Street 600 HP 30005

hey guys got a new fitech unit - dodge 440 built up engine - 470 HP , 727 transmission , 600 HP 30005- in tank fuel pump

she starts up great, idles great and runs great , the issue i cant figure out is that if i drive for extending period of time ( highway driving etc ) she stalls while coming to a stop in gear , if i shift to neutral she picks up but if i come to a stop in gear she stalls ? any pointers on where to start ?

 

Much appreciated

3 things to tune

Raise the DFCO decel fuel cut off enable temp to 300.  Effectively disables that feature.

Raise the IAC loop rate down by 10

Raise the IAC loop rate up by 10

Fine tune as needed.
