Which would you chose and why?

Not trying to flame you, If you think that you will NOT need to tune an SC set-up, you're wrong. This is only true to the initial set-up providing initial boost is not tampered with. Turbo kits are the same way. Initial installation really does not need tuning, as long as the boost is maintained as per the initial setting. BUT, it's your car and your decission. I respect that. I dont know anything about Probes. All I know is that, I've seen some really great tuners who have switched from an SC set-up to a turbo set-up. Dont get me wrong tho, I like centrifugal superchargers.....
