My plan is the different cam and lifters with the delete kit. according to my mechanic he said the new lifters, pushrods etc will eliminate the problem. I hope he’s right, my previous vehicles i’ve never had this issue. The 5.3 apparently has the issue but it’s interesting that mine pops up after 100k miles, well outside warranty. My experience is better than other friends that have the same style silverado.
Changing the lifters and cam should do the trick, lol.
Just don’t use the same shitty OEM lifters - those are what cause the issue.
DFM/AFM is not the.cause, though use a 3rd party device to turn off the DFM (because it sucks) and increase throttle response.
You probably won’t need that since you’re retuning everything anyway.
