I was thinkjng of a choke like cable to hold it open for 2step. But for the most part.. it will be controlled by a electric boost control via link. I will have it openat full boost. The problem Im haveing now is that the turbo Im setting it up for Normally will hit full boost by 4000rpms on a stock twinscroll housing in a undivided manifold. And any bigger turbo will prolly surge like crap before the valve actully opens. I will see how we it works... then maybe invest on a 7blade hx40 or s259bw.
