I'm soon getting a 2011 mazda 2 with an automatic transmission. I've been looking around the interwebs regarding performance (to be specific, power increases) upgrades that can be made to this car. I see talk of superchargers, turbos, ecu chipping, cai and sri upgrades. Just wondering if anyone can recommend which types of upgrades will provide the best value for money, assuming that aside from basic bolt-on parts, I'd have to bring the car to a shop to have the item installed/tuned.

Thanks for your help!
