On the factory boost control solenoid - I am no good at describing, but, it's got a red and black wire attached and bolts on the turbo - there is a nut, with a screw inside. Take the nut off, and turn the screw counter-clockwise a few turns. **-- ONLY DO THIS IF YOU HAVE A BOOST GUAGE!!!!--** If you blow up your engine don't come crying to me! Anyway, loosening that screw will allow you to make more boost.
