$8 bucks later... should be fixed.
Well the good news is you have replaced so much, should be reliable rig now.
Btw I was going to suggest cracked/perforated intercooler , that would get you the surging as well.
What MWD said is correct you need a scanner that can read (and clear) the modules, there is a scanner section on this forum so check that out.
Live data while driving is very helpful, and should help avoid the “throwing new parts at it syndrome”.
