leon fr 140 dsg performance increase

Hi everyone,

I have a 62 plate leon fr cr 140 dsg.
Only had to about 2 weeks.

I have got a stage 1 map witch has made it a lot more fun to drive.
I'm looking at removing the dpf and getting a straight through exhaust and stage 2 map.

Does anyone know what else can be done to get better performance and the pros and cons.
Also is the dsg map worth getting?

Thanks in advance.
