OK after almost going def on the motorways I decided to remove the green induction kit and go back to standard (for the next couple of months where motorways will be my life).
A mate has an RSI identical to mine and hes borrowing it (as he is debating getting one himself)
When he floors it you can hear it but no where near as loud as it used to be in mine. Seriously this isnt just a slight differance, is half what it was.
Both engines are identical
Does one of us have a problem???
Cheers
Tom
