It ran 1.1 since the GT640 was first installed. I made tons of inquiries, and finally decided to adjust the wastegates myself. I'm very glad I did. It's now running great!

I would still hook up a mechanical gauge to double check the boost. If you are higher than target then you will have issues. When the turbos ship they should not need any adjustments. A lasy boost valve or improper gauge can create an off target or incorrect reading.
