Still got MFI on my S2, but not sure what management to go for... and what is out there now...whats recommended?

My car is 200bhp, 220lb tq and that was on a weak actuator. I want more power but not going to go silly on it.

I have the following mods if that helps..

Engine done 70k
Chipped
Stage 3 T3 turbo
-31 Actuator
K/N Induction
T2 cam
Alloy Rad
GRS Intercooler
Mongoose Exhaust

and Koni's and rear discs (just incase you needed to know )
