honestly I don't think you can go wrong with either. I have the SC and like it. I mean, I didn't gain 50 ponies and a bunch of gas mileage but it does help for sure...i run the 91 octane tune with 92 gas, turned my MDS off (main reason I got it, well worth the money just for that). I can say it does feel more peppy with the performance tune, but haven't done much experimenting/comparing to stock to give a good impression. I just loaded it on and haven't changed it since.
So, for what it's worth...I think either one would be good. I'm biased towards SC, and I see a lot of guys run it more than the intune
