How bad is over boost...?
 

Hi, My year 2000 UK turbo has started to boost quite a bit higher than it should as standard. This i persume is due to the ported headers and full decat, Its currently getting up to 16psi (but not all the time) is this a serious concern or shall i just carry on reguardless.....?:confused:

get it sorted mate, if not in time it may do damage to turbo or engine
