The forge 007p will allow you to cope with the new boost figures as well as be more durable as the standard bosch DV are known to break. Induction will make a nice noise as well as allow response. FMIC won't benefit you much on a daily basis only when heat soak becomes and issue, ragging the old dog and summer. I though stage 2 was full exhuast setup, 4FBR, FMIC, induction kit, TIP.
You could have the map tweaked, but I cannot see how you would gain any benefit or performance from a DV and a FMIC, if anything it will run better in the heat rather than that nasty heat soak making the car slower/sluggish. Plus the Induction kit won't make much of a performance gain, if anything the exhuast should see the most benefit and maybe your next mod?
Also the turbo lets the golfs down, k03 is ok but does not go far maxed out, k03s will be a better choice, after that there's other turbo options its all down to what you want to put out.
