Hello everybody. I’m getting these codes once I went to tune my car and it wouldn’t take the tune. It kept having a very rough idle and stalling out. I’m FBO, have 18t turbos, and it's a manual swap. I bought the car yesterday. I put it back to the stock tune and now it doesn’t want to idle correctly. I tried 2+, but it wouldn’t run right. 2 wouldn’t run right. Stage 0 nothing and now back to stock still running terribly.
It was running perfectly before that. I did a throttle reset but every time I clear my codes it won't hold an idle. Thank you so much for your help and your time!

If youre running hybrid turbos with inlets on the stock tune i can see this happening. You absolutely cannot run an off the shelf map with hybrids and inlets. Also, when doing a throttle reset make sure to follow the directions very closely. Otherwhise your idle is going to be all over the place. Ive had my fair share of missing a step and my rpms would jump all over.

Agreed with Slow, make sure you wait the 30 seconds after tuning like MHD states once the tune is complete

I am actually having the same exact issue right now. I have 17ts and every bolt on part you can think of, I had an old 17t map that was flashed for a really long time so I wanted to change some settings but after I flashed it I got the same Boost overrun (2ABD) code.
So I flashed to 2 and it still was in limp mode

Now I am waiting for my tuner to send me a new custom map and I hope this fixes my issue

I have the same exact symptoms, very bad idle and it stalls out when I put it into gear, and some random misfires as well. I will keep you updated and hopefully I get my car running good and I can help you out.
