I've had literally every clutch possiblity from SE to SVT to every stage of Spec clutches, and I'd only recommend a stock SVT clutch or 3 or 3+ for any build. If someone is going for a beast N/A 3L, even with a small shot of nos, I'd still recommend the stock SVT clutch as it was made for longevity and it still is a wonderful not chattery and hard grabbing clutch. If you car going for boost or a huge shot of nos like you say, I'd go for the stage 3+ if you are worried about driveability. The stage 3+ being a full face clutch is pretty easy to drive daily, but like all spec clutches you can expect clutch chatter. The stage 3 is a great clutch if you either want to save some money and therefore sacrifice a little driveablity or it is a perfect clutch if you are someone who does lots of burnouts or takes your SVT to the track. The stage 3 is better for crazy driving and launches as it is the 6 puck design instead of a full face clutch so it has better cooling characteristics. I personally went with the stage 3+ in my 3L turbo for the longevity of the clutch as well as the daily driveablity. Both will hold more power than we can throw at them so that isn't the issue. I just knew I wasn't ever going to be doing burnouts or hard launches in my 3L turbo as I would go nowhere so I figured I'd spend the extra dime and go with the stage 3+. It is all a matter of opinion but I never like my stage 2 or stage 2+ and I'd avoid stage 1 because you mine as well just go with a stock SVT clutch if you are going stage 1. HOpe this helps a bit.
