Owners of the Super AVC-R: Is this unit really worth it? The basis for this post is because I'm in need of a boost controller, but I wouldn't mind getting a fuel control and boost controller in one.

Question #1: Tuning: Is it a problem, truthfully? I've heard nightmare stories about tuning this unit. I'm not a beginner by far, but have never used self-learning modules like this.
Question #2: Has anyone had problems with the functions of it? I'm talking about trying to tune the fuel delivery. That concerns me the most because I'm running 9psi daily.

Thanks in advance...
