Hi, I've got a B6 quattro with the k03 turbo fitted, I have had a stage one remap done to the car, while the results are great, I'm in the pursuit for more power and upgrading the turbo.
I eventually want around 250-300bhp, I was thinking of the k04 or the T28, if install them without remapping the car, what will the results be like? or will it defiantly need a remap after installing?
And what things can I do without upgrading the turbo to get more power? If i was to upgrade the injectors, would that give me more power without having to do another remap?
