God. Photoman your cynicism brightens my day everytime I see it. It makes me feel I'm just a LITTLE better of a person each time. Haha. Just razzin.
To answer the question...you don't "chip" these cars, thus photoman's (deserved) cynicism. Search for "ECU" and start reading. In this vehicle you'd be looking at shipping your ECU out to someone like LET, TVT, Inmotion, and the like, and life would be good. As far as what's best...an ECU tune can only be done so well without dyno work, so you'll just have to ask around.
Also, check out the TVT 250, 265, and 265+ kits, they're just wonderful

oh and how does the borla sound?
