Funny I still remember all the codes I've got in the past. Most anyway
30ff is the dreaded boost leak. Can be anything or as simple as a disconnected vacuum line.
2ded I got once after hooking my battery back up. Cleared it never came back.
The 29f4 and 29f5 might be from no cats in your dps, i think that's what came up when i did my dp install and had yet to reflash mhd. But i could be wrong, was awhile ago.
2a15 i got when i broke my vent line connection on my lpfp it came up as a loose gas cap.
And i think the others have to do with coils
The first couple 29 ones anyway.
Are you sure all your coils are installed correct?
