60% (closed) is the default WG position that is set in JB4.
First things first:
Look at the DP clamps, should hopefully be able to see them from the top. Make sure that the part where each bolts together are nowhere close to being in the path of the WG actuator or swing arm on either turbo. If either is, you’ll want to loosen the clamp just enough to spin it to a different orientation completely out of the way and then tighten it back down. If neither clamp is potentially blocking the WG, need to move further.
Not sure what turbos went on or it they were new or rebuilt, but it’s possible that the WGs themselves were put on way too tight. Other than that, something wrong with the boost solenoids would be the only other thing I could think of right now that might cause uncontrolled boost.
On the JB4:
- Feed forward is at 149 (150 is max). Set FF/WG adaptation to like 50 in the interface settings tab.
- Reduce the DWP to 20-30 in the interface or dash menu.
- Set boost safety to 16psi in the interface to keep it from getting out of hand
- Set dash menu 4 to 3
Boost safety tripped will cause an engine malfunction light and you'll need to pull over and restart, so just be aware. Save any logs running before you restart.
