My mods:
Bms intake
CP-E chargepipe
Procede v5 rev 2.5
Custom downpipe/ exhaust single 3" all the way from turbo back.
Wow that is crazy... so you feel like its sputtering but you dont see the rpm change at all? hmmm
Yea I'm pretty sure it's probably the exhaust dp and weird flow haha. When the car is driving , it's completely fine it's just when I'm idle
