I'm working on the truck in my sig. After installing all my upgrades last fall (pac brake, hx 35/40, 100 hp injectors, quad unit), I haven't been able to get over about 25lbs of boost even with the set screw in the boost elbow turned all the way in. Today I put a vice grip on the hose and saw a bit over 30ps of boost on a full throttle acceleration. Where in the adj process do I check the actual wastegate actuator setting/position? Its possible correct, to maybe need to adjust the length of the actuator rod? 

 

Also, I bought the manual boost controller shown by Mike in another post and have yet to install it. Mike, the red end goes towards the elbow correct? 

 

 

 

 

The red end to the elbow, the blue end to the wastegate.  The manual controller's internal spring is very stiff.  I shortened the spring to get a lower psi adjustment.  About 30psi is the about the max boost a stock HX35 will produce.
