Hi guys, since I have almost decided to keep my Audi now I would like to know exactly what I can do on the engine. Budget is 1000€ Ne Group A system will then probably get to BN Pipes, which is of course not included in the 1000€. Then I would like to know what distinguishes my PS from NG. Recently I read that they are largely identical. Could I (let) convert the one to NG?
