Hey everyone, I'm running a gcg highflow on my r33 gtst and my boost control methods include a greddy profec and hks adjustable actuator. Even though i have adjusted the hks actuator by changing the length of the rod, I have boost tappering off in higher rpm? I beleive this is due to the fact that changing the rod length is only changing the preload etc... So my question is, what actuator should I get in order to hold 20psi, and where can I get it from?
Has anyone used the Power Enterprise ones? refer to link http://www.rhdjapan.com/power-enterprise-s...-actuator-57475 any thoughts on these?
