I'd not bother with a generic superchips remap... if you must tune it find a very good independent who has had lots of experience with the valvetronic systems and get a full remap done. It'll cost you a lot more, but it'll be much better too.
Or, just leave it standard and invest in other tuning areas, because the extra bit of power available won't really add much to the driving experience... also, you leave yourself open to the compromise a tuner wants to optimise for.
I'm tempted to remap my car, but I'll be doing it myself and I'll just be adjusting the throttle mappings to make it smoother and use all the travel more (while most tuners actually just map it sharper and make it 'feel' faster without actually being so)
It is a can of worms really, but a good NA engine is already usually tuned pretty damn well, so a remap is only really ideal when big changes have been made to optimise for!
