Something else has to be part of the equation to make it all work. Don't get me wrong, the guys at LET are great and know their stuff but they aren't just doing a tune and bolting up turbo's or SC's. If they were, we wouldn't have a thousand threads titled "can I add a supercharger/turbo to my car", we would have a thousand threads titled "dude, I just added a supercharger/turbo to my car and holy jeebus"
Think what you want. I have seen it with my own eyes. Nobody has said anything about simply throwing a tune at it, but you seem to have it figured out.
