Are you getting a bad shutter on the top end? kind of hard to tell in the video!
Check you steering shaft bolt, the one where they slide together under the hood. Had the same issue on the race truck, bolt was loose.
OK since you are still dancing around the question :fluffy:... Let me word it a different way... :confused:
If the wastegate was disconnected and the port on the compressor was blocked off, would there be a boost level change?
Is this from personal experience or just hearsay? Because i know quite a few trucks making over 1k to the wheels with our Mahle cast pistons.:confused:
