Okay, first off, dont use the Wizard.
In the Settings->Accel Enrichment screen set the dv/dt values to
- =1, [1]=5, [2]=20, [3]=40
then in the enrichment values use your 0.3, 0.6, 1.2 and 2.4 values - you'll probably find that you need to re tune these.
This will help with tuning but I am not sure if it will help cure the RPM issue.
