Well, im happy becuase it finally came and i got it installed. the DV noise is a little bit louder...but im angry...im still only boosting about 15 psi. fluctuating to 16 sometimes.

earlier, i fixxed my boost leak adn i was boosting till 21 peak, the it died off. i thought my DV was going when i was peaking at 16. i replaced DV. old one was fine. new one is awesome. but still only boost 15-16 peak.

is that normal? what...??

 

Check for more leaks cuz 21 sounds right for your spike boost.
