Message issue.

Here's my previous thread on the matter starting from the relevant post.
In the below link, it was discussed and confirmed by a few individuals that setting a wastegate pressure of XX(psi) would yield XX(psi) minus 2-3psi actual. Therefore, if you're going for 10psi of base boost(like I was), you would want about 12-13psi at the wastegate.

Another thread followed later by someone else.

Furthermore, the autoFAQ had a great write up.

Sorry for all the links. For future individuals and search purposes, I'm trying to determine if I synced them wrong, or the lack of info in all these posts as to just HOW MUCH the flapper should move to consider it synced. By the FAQ, and everything I researched, it's just to the point that the wastegates break/crack open a hair.

My issue is that I synced my wastegates to 12psi just to the point where they slightly crack. As stated above, I was shooting for 10psi. What I'm getting with my boost controller completely off, and again confirmed with it being on at the lowest possible setting .2 bar / 20% duty that BOTH times, I'm peaking and leveling out at 1.25 bar/18psi.

So what's exactly the issue here? I'm shivering at the thought that I'm gonna have to drop my tranny & remove the DP's to re-sync them.
