Boost Pressure Control Issue

Hoping to get some insight into what’s going on with my car.

I pulled it from a 4 month storage period a couple weeks ago and has now gone into limp mode 3 times intermittently at different degrees of throttle. I thought it may be a JB4 related issue so I’ve been running in Map 0 but still having the issue. Error codes coming up: 30FE (Boost Pressure Control 2), 3100 (Boost Pressure Control 2), and 29DC (Cylinder injection shutdown: low injection pressure). 3100 is the only code that has come up each time, the others vary. Sounds like it’s running fine, not experiencing any misfires, idles perfectly, no visual signs of vacuum leaks.

Does anyone have any idea where I should start on this one? Any help that I could get on this would be much appreciated.Thanks.

Check vaccum lines and wastegate actuators.

Lines and actuators look alright. Could something this small have caused it? (very zoomed in)

Old thread I’m hoping that you may still remember what ended up happening when you took it to the shop.... I’m also getting the 30FF code. Do you recall what was the fix?

I went through EVERYTHING... I turned out to be a conflict with my JB4. I had a back-end flash which resulted in the 30FF all the time in Map 0.

Hope this helps!
