Hello Jimmy.
I Had a carbonio, the car was'nt mapped at the time though, so couldnt really feel much of a difference!
Since having her remapped i installed Nuspeed P-Flow kit, now its nothing drastic, but you can definatly feel more pull mid to high range, makes a lovely induction sound too! subtle roar, without sounding chavy
Forge make a Twintake system, heard nothing but good news about this bit of kit! Personly i think you really need to go the full turbo back complete exhuast system + cai to really benifit in real power gains!
