P0299 and limp mode

What is your question?

Drive a 2014 tdi jetta. Fully deleted and tuned, hit a pothole and as soon as i put it under a decent amount of load it goes into limp mode and throws a p0299 underboost code. Checked for vacuums leaks and there were none. Maf is at 15g/s at idle and seems high even though its brand new also has a p0135 o2 heater code that popped up afterward. All boost pipes look fine and it only usually happens when i hit around 60-70 while hammering it.

How long has your 2014 Volkswagen Jetta had this problem?

More than a month
