Difference in BHP on 1.0

Hi all

i noticed the 1 litre 92-2000 has 54bhp and the 2000 onwards has 59bhp.
does anybody know where the extra bhp is coming from for example in the ecu, head etc etc
or is mix of little tweaks

cheers
 
Different CAT design aswell isn't it, slightly longer and no second CAT, more free flowing maybe? Dunno if that contributes.
