Yes. The 2.7 Turbomax has Active Fuel Management. It is NOT the same as the V8s. Totally different system.
Here is an article from GM when the 2.7 came out explaining the cylinder deactivation and the valve lift system. Starts at the section called "SCS Valvetrain":
New Turbocharged 2.7L 4-Cylinder Engine Powers Full-Size Trucks – TechLink
This is an internet myth going around. It was alleged that some 5.3s had this mystical 8th digit of the VIN as an "E" which somehow meant it had a new one year only 5.3 that didn't have DFM. The writer of said article and the person that made the claim conveniently can't count because they posted the VIN. The 8th digit was a "D" which meant its still the 5.3 with DFM. The 9th digit of the VIN was an "E" and the 9th digit isn't the engine code. At all.
Well, before I bought new TPMS sensors I'd test the batteries, or the heck with it; just put new sensors in with KNOW GOOD BATTERIES, dont just trust batteries just because they are new to you.
To make things simple, general rule of thumb is not to exceed 80% percent of manufacturer's stated max towing weight to avoid white knuckle driving and that is with a WDH.
@EJS2015 about the cable to connect the front camera. Did you use Female to Male ? I think I saw someone using Female to Female. Im trying to confirm before buy the cable.
Thank you
