    Now that's 14 different setups.
    I think our cars doesn't have vanos, which is a variable valve timing. So we can remove two from the first bunch, 5 from the second bunch and one from the third (I'm assuming when some data is variable it means it's for variable timing)
    Also we can remove the sport ones in the first bunch because they don't have a good idle (race application)

    it gives us that:

    In the ones left, which one should I pick?

    By looking at numbers by myself, they are all pretty similar, the third one seems to be the mildest of all. The three others are almost allt he same, witch all slightly different numbers.

    Now I need someone who knows cams to guide me from there.

    A higher duration is going to allow more overlap to make greater mid to upper end power, at the sacrifice of low to mid range efficiency (which is why the idle becomes lumpy when the durations get too extreme).

    With this in mind, knowing that with the Kleemann K23 kit, the supercharger has a tendency to overspin at high RPMs, this would be a bad idea if you are so-equipped.

    Otherwise, I'd go for the 260/264 setup and get the ECU reprogrammed accordingly, possibly with a higher redline if the motor can take it.

    no I have an ASP which doesn't overspin the SC

    I think the biggest drawback from my experience is that the powerband, although more potent, will become more narrow and peaky (depending on the cam specs). In my case, with the automatic trans, it's not really that attractive of a mod.
