Hi and welcome to the forum
Is your current car a manual ?
As Hurdy says, only you can really answer the question as it depends on what you really want from your car.
Seems to me like you have two questions to ask
1. Do you want DSG
2. Do you want an ED 30
If it was me, I would'nt change for the sake of it, but I'd wait until I needed to change car. I don't think you'd have much "more fun" by upgrading as they are very similar cars. I waited until my finance was up, and then changed from a DSG GTi to a manual ED30. My personal preference would now be a DSG ED30 with 18" Monzas ! Maybe next time for me

If the time is right for you to change car, and you can afford it, then why not go for it - ED 30 DSG and then a possible remap to 300bhp 3 months later ? That would be my choice

Most reputable remap companies will also give you a free trial, so you can experience the difference - where do you live ?
