Pop then a CEL when hitting the highway. Loads of ECU Codes thrown.

I was merging on the highway last night, went to accelerate then heard a little pop and then the truck went into limp mode. Power sucks and tranny shifting all over the place. I was hoping it was something as simple as a hoseclamp but those all seem to be secure by the intake and intercooler.

I threw the following codes. If I clear them some come Back and others don’t. I was going to try to reload my tune hoping it would reset everything but now my SCT has a “download error, return to stock”

codes tossed. Know I’m missing 1-2 that logged.
P0299
P0555
P05B0
U0298

Thoughts on where I should start? Those codes are all over the place.

P0299 is underboost. The majority of the time when you hear a “pop” sound and set that DTC, a charge air hose is loose/disconnected. You can’t tell with just a visual inspection, often the hoses will blow off but still appear to be connected. You have to physically check each charge air hose connection to verify that it is fully seated and secure.
