Hey guys! I'm having an issue with not getting over 5 psi of boost. I can rev out to 6 grand still but don't build anymore boost. Usually builds about 12 psi. I used a vagcom system and the problem stated a bad n75. Which I replaced and it fixed my boost cut problem but I still can't build boost over 5 psi any ideas?
Thank you
