Can anyone tell me what types of performance upgrades there is I can Add to my Mini Cooper Countryman. It feels a bit lame and would like to add atleast another 20Bhp. Is it possible?

Not sure what's available specifically for the Countryman, but remap-wise check out Bluefin (http://www.mybluefin.co.uk/) or try Evolve (http://evolveautomotive.com/) or Performance Torque (http://www.p-torque.co.uk/). :)
