Sct is good when I called, anytime I'm on hold longer than 5min.. with anyone I hang up. Call right back and you will get someone. To get stage 3 map, you have to have stage 2 with toys pcm. That's the only way, Stage 3 pcm is the only one that can add toys, even if you got stage 3 no toys. The stage 3 pcm has toys no matter what.
So if you have stage 2 with toys pcm, like I do.. then you can get the Stage 3 with toys map. If you don't then you can't.
It possible to data log a stage 3 car and copy and paste, but you won't have HOM.
Most will say you don't need it, just a good tune.
