| 1st: are you running restrictors in the oil feed lines? 2nd: improper wastegate accuation can cause one turbo to over spin to reach target boost due to lazy turbo on other side. examples: -stuck open wastegate on other turbo -sticking gate (flap hanging up on downpipes, linkage from to flap haning up, rod hanging up on oil filter tree/bracket) -un syncronized wastegates (turbos with adjustible wastegate rods should always be bench tested to make sure the gates open equally with eachother) -improper reference signals to wastegates
