Obvious next step is stage 2 which needs a downpipe, and an intake upgrade will help. You can then look at FMIC and the k04 turbo upgrade but personally I believe you'll make a faster road car with chassis/brake upgrades rather than chasing bhp.
I have been stage 2 since December with Revo software, Blueflame 3" TBE and a Carbonio intake.
Next up is a Helix Organic Clutch, TTS short shifter, Bilstein B8 shocks, H&R ARB's, Superpro ALK, Vibratechnics lower subframe mount and dog one mount bush.
Brakes I am still not sure what way to go, but trying to avoid .:R/S3 calipers due to their weight. My tuner reckons he an fit Aston Martin 4 pots with bigger discs all brand new for a sensible price

Then it's just some lighter wheels as the Monza's are so heavy and some decent rubber......oh and maybe a Quaife diff.......
