Hey ppls,
Well I did thi slittl emod the other day and found that boost response was improved, but unfortunately it was raingin at the time, so all fun was hampered by bulk wheelspin.
Today however, driving back form the airport, there was no rain and I can say that I am quite happy with the mod.
I used a grub screw into the hole after tapping straight into the aluminium, therefore I can remove it at any time.
Oh, and the BASS OUT thing is like the OVER AND OUT but my own personal little one. More of a remnant other internet forums which I have been a party to, and thereofre it just caries over.
So,
BASS OUT
