I havnt got the cash yet to start tuning the 330ci. I have been wracking my brains trying to think of free ways to make her a little bit quicker. Firstly I have removed all the things I was carrying in the boot, this came to just over 70kg!!! Next i removed every thing from the boot, and i mean everything.. Sound proofing has gone, carpets have gone from boot floor and arches, CD changer gone, spare wheel gone. Sound proofing from under rear seats, inside door cards and under bonnet all gone. Now I know from removing all the sound proofing I have only saved around 10kg, but every little helps and I honestly cant notice any sound difference when driving. I want to keep the car looking as 'normal' as possible so seats etc will be staying in. I want to remove the air con system, as it dont work and the last few cars I have had it hasnt worked and I havnt missed it to be honest. Anyone got any tips on removing the air con system before I get my spanners out?
