Too high of crack pressure typically can cause an overboost code. Easily addressable.

Ecu would catch the boost and use the boost controller to acheive the target. Essentially not a big deal within reason.

@@JohnWSRD so if you drop down in fuel e85 to 95 octane when u change your ecu to lower boost to run 95 technically you don't need to drop your wastegate from 11 to 9 lbs?

As soon as the wastegate rod moves outward, opening the wastegate flapper. That's what we measure what PSI that is "cracks" at. The wastegate when pressurizing the wastegate itself will sometimes look like its pushing the rod out. But, we don't consider that proper. It's when the rod itself actually moves.

If its not opening correctly, weak or compromised (binding) spring. It will cause improper boost control. Leading to that, sure.

Air meaning exhaust coming out of the v-band clamp of the turbocharger? There is suppose to be a metal "v-band" gasket there. It shouldn't be leaking though.

I can't feel air coming out of anything, and you know hot fast everything gets hot. I was wondering if it was coming out of the wastegate? If anything it sounds like it's coming from the exhaust.@@whalensspeed

6 PSI.

Yes you're using pressure.
