Intake upgrade, now "huffing" noise at hwy speeds
Earlier this month I installed the Banks Ram-Air Intake system on my 2005 6.0. Everything went smoothly and no driving problems. That is until I took it on the interstate this week and had issues when driving at 65-70mph with cruise control.
When going up an incline it sounded like the engine was huffing or trying suck more air in short spurts. It would also make this same noise when I would tap the brake pedal at highway speeds to cancel the cruise control. This problem never occurred when driving without cruise control.
On my return trip, I noticed that there were far fewer occurrences of the huffing noise on inclines but still happened at let up after tapping the brake to cancel the cruise control.
Looking for ideas or input from those experiencing the same issue.
