Who can recode in Sydney?

I've just completed the Alpine audio upgrade on my e91. It amps the subs and front speakers. Front speakers are replaced and adds tweeters, the rear door speakers are unchanged and powered by the head unit output. Miles better than the rubbish base system but it's a little boomy, so far as I can tell it's because the output is high level and pre-equalised to make up for the fact it didn't have have tweeters before.

Is there anyone in Sydney who can recode, specifically code the base unit to either Hifi or Alpine Hifi? BMW want $255 which doesn't seem too bad but won't guarantee anything.

Thoughts anyone?
