Hey guys me again this is my first diesel and i'm learning more and more everyday,but since my mods it makes funny noises sometimes especially during acceleration it kind of makes a low pitch rattling sound and if I stomp it hard it like stops for a second and then takes off like a jet. it sounds fine during higher acceleration ,it jst seems to sound funny right before and during kickdown. My buddy said the rattling was do to increased timing but all I know is it sounds wierd and makes me think something is wrong ( p.s we hooked it up to a scan tool and found nothing wrong.
