now i know what that roaring sound was,,,,,,first time i heard it ,,i thought,,somrthing happened to the engine,,was pulling a 20ft trailer and had gotten off the interstate a mile or so back,,pushed on the go pedal and she roared alright! startled me! i only heard it acouple time since, but don"t remember the circumstances

 

forgot to tell ya"ll,, the first time i heard it,i was in tennessee,and it was july, and it was hot,probably upper 80s

 

40 or 50 degrees in Mississippi in the summertime? I would suggest you move to Texas
