Why do i have the loudest 7.3 around?
My truck is extreamly loud and i just dont know why. I ran 3/8 SS tube from fuel tanks to motor eliminating all quick disconnects. Both fuel tanks have same 3/8 SS pick up tubes with the return lines as far from pick up tube as possible. DIY stage 1 injectors made it a little quiter but not much. TW chip made it much worse and now it just drives me crazy. I spent a small fortune on dynamatt and extra insulation under the carpet with no difference. Truck runs great and has always been stronger then most other 7.3s i have driven. Motor has about 233k miles. Any ideas???
