Wife wanted her car to pop on decel like her old 1968 Chevelle. I changed the dfco values in the enable VSS to 45 and the disable VSS to 40 and got some results, but she wants more. Not sure what else is safe to change. Any help??

I was thinking of adding a wee bit of fuel at low load and retarding timing in the same area...2000-3000rpm.

I looked at the Open Loop decel load table...all the values are 0.00. To add a bit of fuel which way would you go, plus or minus. I just want a small change. Maybe suggest a baseline guess would be of great help...I can work from there.
