i have a hks race wastegate 50mm with a 11psi spring trying to controll it with a greddy profec b boost controller. The problem i have is when i turn the boost controller on can't boost no more than 7psi, but when off it would go to 15psi on a 11psi spring. i have vac line frm turbo to in on boost selniod and the top nipple on wastegate to out port on selniod. I have side nipple on wastegate going to intake manifold. i needed help been trying all weekend to get it to wrk properly and also have the dip switches on bck of controller set for external. pls could someone send me a diagram on how they got a profec b in stalled on their 7m.
