Is this boost leak?
hey all,
I was wondering if I have a boost leak or is this normal.
I have a defi boost guage and at idle it reads -10 lbs. But the moment when I engage the clutch to shift up while driving, the meter goes down to -20. I'm curious to know if this is normal or if I need do do a boost leak test.
Any help is appreciated!Thanks.

Realistically, it doesn't take long to do the test. The hard part (might) be fixing the leaks.
Also, FWIW - some leaks you can't notice and in your case, even if you could tell (tell tale sign is loss of power, spool up and over-boosting) you would have to be in boost (greater than 10 PSI, not in the 'negative' (vacuum) region to which you were referring).

This is completely normal. The higher rpm of the engine + closed throttle plate produces greater vacuum than at idle.
