hey guys... well i got the external wastegate hooked up off my manifold along with the evoIII turbo... when i run boost off the wastegate and disconnect the boost controller... it holds at 12psi until redline (running boost off the spring...) its a tial 38mm wastegate.... when i hook up the vacuum lines to the boost controller the boost is no longer controlled... hitting 26+ psi... i was wondering what type of manual boost controller you guys use, and recommend.... thanks
