I recently bought a 14psi spring for my turbosmart wastegate because I haven't purchased the boost controller that I wanted. I'ts boosting to about 11 psi. I was wondering why that was. The line that goes to the manifold fell of and it actually boosted to 14psi. but when I put the line back to the manifold it was boosting back at 11psi. I was wondering if the manifold pressure had something to do with it or the blow off valve or a leak in the manifold. Do you guys have any idea?
