Hi, just want to know if it's anything to worry about!

I have a 02 plate vRS and have noticed a very slight whistle when accelerating. The car is standard apart from a CAI and had the normal induction/turbo whooosh before I swapped the Bosch dv for a 007p and wandered if the forge dv changes the sound in any way. Any help appreciated!!!

Depends, probably normal but could be a boost leak.

Have you ever had a turbo car before? :think:

Had a octy mk1 vRS from New for a year but kept it standard so just had the normal turbo noise. Suppose best bet would be to put the Bosch dv back on and see if its still there.
