HPTuners has a HUGE learning curve if you're new to EFI tuning.

Turning off VATS is one thing, but working with the multitude of tables and understanding how they interact is another. Want to set the IAC becuase the rolling idle js hanging? Use complex tables in g/sec airflow. Going lean on tip in? Back to the bizarro throttle cracker tables. Aftermarket EFI such as Holley have thankfully simpified the tuning tables and made it easier to understand.
