Yea I've been looking to get a new n75, will pick up one when I get the chance but timing belt next... What sort of difference should I expect with a new one and an adjustment? (sorry for the thread hijack)

Proper boost level of 15psi.

N75's are not just 'working' or 'not working'. They can be lazy and leaky. I consider it a wear item and part of maintenance.

Get a cheapie db meter or use the free app on a smartphone if you have that. It'd probably be easier to compare. I'll drive around in mine and let ya know where it lands. Streeker has a good point. We have no baseline.
