Didn't see the first post, but I'd start with the wastegates (vacuum hoses, cleanliness of the actuator rods). After that I'd look at the intake (anything from outlet side of the turbos on). If none of that pans out, I'd be looking at the turbos.My 99 turbo is Esprit V8, turbo is not working properly. Its giving me very low boost. Is there something I can check at. First part of this posting was posted under Elise, that post will explain better. Thanks in advance !
