We were having issues holding the correct amount of boost, it would hit 8 psi off the bat and then dwindle down and hold 6psi when we used the mechanical boost gauge on the Dynojet at another shop in town. Installing that boost controller yesterday and leaving it at wastegate boost has made a difference on when the gate opens and it feels more steady. I'll give some more updates when I have my gauge situated and I'm on the dyno again.
