I have a Jetta 2.0 tdi. I want to do away with the egr, and stock downpipe just so I can get a little more power,efficiency, and air flow from the motor any tips would greatly help I am new to diesels and also vw so I dont know what I'm doing lol. Do I need to tune the car after doing these things or will it be fine and not hurt the motor to do these things and not tune it at all?
