Just as the SC pulley had some problems in the beginning, it too could have been caused by install error.

I like the sc option and if I wanted to hit 11.5's then I'd look into tuning for the proper sized one in a combo situation. As for 11's with just the pulley on 110 octane, I don't think it's going to happen. Kudo's to the first who does, and I will be the first to congratulate. Even with -250 DA gator went 12.22 with stocks. That's with some nitrous in the air. 12.0's will be a challenge to meet.
