Yes it is the tremor system. I only drove it 5 mi down the freeway with the cruise control on. I didn't notice any annoying sound from the cylinder deactivation.
Yesterday I installed a Corsa Sport exhaust. The Install went great and I am very pleased with the sound. My truck only has 1100 miles on it so the factory system came apart without any trouble. Made for a fun morning installing the system and a fun afternoon cruising around with the new exhaust...
2/10/23. Was shocked when the truck arrived so early. When the order was placed The dealer told me it could be May before the truck would arrive. Went to production on 3/24. On 3/26 I received the email from Ford with a delivery window of 4/4- 4/10. The truck arrived at the dealership on 3/30.
I've been lurking and learning my way around the fourm here for the past few weeks while my truck was on order. I just took delivery of My first F-150 on March 30th. 2023 Platinum 701A, 4x4, 5.0, 3.73, Antimatter Blue, BAP, Moon roof, interior work surface. Looking forward to starting mods soon.
