I wasn't aiming for power, the car is more for track use so handling took priority, can't recall exact figure, but it is over 300bhp and also over 300bhp per ton. It's not a great deal of power but it's enough to be competitive on slower circuits and fine for street use.
Next mod for you is difficult to say without knowing what sort of power you're aiming for. Most people wanting a bit more would go for a good flowing exhaust, decat, larger intake pipe, uprated actuator, good flowing front mount intercooler, s3/TT injectors, uprated fuel pump, water methanol injection and a stage 2 remap.
It goes without saying if you looking for 400+ then the above list is quite useless. I'm guessing this is your first attempt at modifying a car, its a good idea to familiarise yourself with the amount different turbos are capable of flowing.
