Well that sucks. It was back firing through the intake. It had a tick this morning it had never had before. Its definitely a lifter. Mechanic will start tearing the engine apart tomorrow. Its not good boys. Looking at 2-3k.?? The mechanic is also going to do compression test before tear down.

If you check out AFEs intake or exhaust for our trucks, they have a factory dyno pull on their site. Then with the bolt on dyno.

I was starting to get a misfire, also it was like my truck hit its rev limiter at 4k. I've been looking around on here at different issues. I think mine is fuel system related. It backfires once followed by being sluggish. With that being said today was the worst. I dropped it off at a local shop. Ill know more tomorrow. Good luck to you all.

I have a 2015 1500 silverado. A few months back I was having similar issues with no sound. Purchased a new battery for the truck and I haven't had a problem since.

I have a 2015 silverado 5.3 4WD. I've added AFE intake, AFE exhaust, Edge throttle booster, and the edge handheld programmer. Also about to hit 120k on miles. The way my truck acted its making me think fuel system. Same studder, hesitation you all describe. My truck is at a local shop. Tomorrow morning they start on it. Hoping to know something soon. I'm thinking one of the two fuel pumps. Maybe a filter? Also I'm probably going to have the plugs, wires, and maybe coil replaced. Once I know more I will bring back what I learn.
