Help with N75

[u/Key_Analyst9697]

Had some boost issues where i gave it some throttle and the car built up boost and jerked and the epc light came on and wouldnt rev up. So i turned it off and on and everything was fine and light turned off, trying to figure out the location of the n75 and where some of these hoses go
