So I go down the road and get hard on the S2k... Notice I am boost creeping anywhere from 11-15psi (on a 7psi spring) from 7000rpm to 9000rpm (on race gas). I had the EMS hooked up and my tuner in the passenger seat when it did this... It shocked us both.... The motor held the boost just fine, no knock or anything... We checked the lines to the wastegate (no boost controller hooked up) and everything is ok... Have any of you heard of HKS wastegates failing? It was fine a couple days ago, and then all of a sudden it does this... Ideas? B.
