I've seen several of these vibrate under a 100% throttle when the boost goes over 38lbs.

When it's vibrating try backing your foot off the throttle slightly till you boost goes down to 35 or so and see if it still vibrates.

If you find this to be the problem then you over boosting the engine, and you need your turbo closing and opening adjusted.

It doesn’t make any difference what the boost is, as soon as it gets to where it’s working it vibrates. I’ve seen where many ppl complained about this type of vibration on these. Must be a common thing, I’m just worried the engine will come apart again!
