I realize thier is a lot of threads with similar questions but I was not getting a clear answer. I have s&s 2-1-2 power tune duals, v & h 4in slash cuts, and stage 1 a/c. On the pcv website they don't offer this tune which tune is the closest. True duels, 2-1, or 2-2.

 

The S&S head pipe is not actually a 2/1/2 design, it is essentially a true dual with a balance tube. For a base map I would start with the closest true dual map and Auto Tune should have no problem populating corrections.

 

Thanks, I guessed right hahhahaha
