I haven't had a chance to drive my truck very much since I got the Edge Race and deleted the dpf. I am getting some turbo noise when I try start to give the truck fuel kind of easy on levels 5 thru 7. This only happens in 5th gear. It almost sounds like the turbo is spinning out or coughing . It isnt really a miss but that is what it reminds me of. If i really pour the coal to it it doesnt do this but of course the clutch doesnt like that very well.:banghead: I am sure some of you guys know what this noise is and if this is hurting my truck. Thanks
