When I'm just cruising and get up to around 80-85 mph if feels like my truck is sort of surging. I have the bullydog triple dog power pup on it, just changed the fuel filter 500 miles ago. I noticed it has a light haze at idle which would be injectors. Could it be my injectors causing this or starving for fuel? if I romp on it, it will get up and roll at that speed, that's what is making me think it could be the bad injectors doing this?

 

Maybe but I don't recall my injectors causing surge, and my injectors were really bad

 

that's why I'm wondering if it being on the extreme tune and the combo of bad injectors is making it starve for fuel

i guess it's not really surging, it's almost like a slight miss/hesitation almost while cruising at steady speed at around 80-85mph
