If you mean "enhanced" scan speed and you're using an ion trap (linear or LCQ), I'd highly recommend choosing it. The scan speed is slightly slower than the normal speed and allows for better mass accuracy and a better chance at seeing the charge envelop (thus better able to determine charge state). I have an LXQ and find that when I use "enhanced" I get mass accuracy approaching +/- 0.2 - 0.5 amu vs unit resolution for regular. Of course this only applies to profile data, I don't know if it's even an option in centroid collection mode. I also use it for my ms/ms.
