Well, I'm not against it necessarily, maybe wary is a better term. Its a daily-driven car that does a lot of miles in the summer, and I've heard the alpha-n tune for the S50B30+carbon is less reliable/stable, etc than the S54.
As I understand it, there has been a lot of effort put in to finding a decent alpha-n for the S54 (by shops like Evolve) but not so much for the old S50B30 (understandably). Did Stance do your tune?
