I wonder if the big name shops tune VE in the cars they do.
I don't think its that hard, mainly depends on how OCD you are on how perfect you want to get it.

Use the bluecat VVE coefficients generator, the HP Tuners built in one just isn't that great and the solver in it will get really unstable between boundaries and screw up your smoothness of your table and change parts of the table you don't mean to change.

I agree 100% you have to tune VVE and get it right if you want a good idle. I also had to adjust the virtual torque table by about -20% or so in the idle regions and only on the negative and low timing tables. Before I did this it would idle at really low timing values and made the exhaust louder.
