A few weeks ago my 2010 Silverado LC9 with 90,000 miles had a lifter collapse on number 6 and it destroyed the camshaft. I went with a Non-VVT delete kit with stage 2 cam from Texas-Speed. Everything is going well with install, but just a slight difference with the mounting bracket from the Camshaft sensor doesn't work anymore. For any whom have done this delete for 2010+ 5.3, do you just cut the wiring out and leave it hanging there? Or modify the bracket for the pigtail by grinding away parts of the bolt ear area, and cutting/bending other parts of it to make it fit? Or the last option is to buy GM P/N: 12627501 that appears to be the pre-2010 camshaft sensor mount.
Just trying to see what most do, and proceed from there. Thanks for any input you provide.
I am new to the Forum and have a 2017 Sierra with 12K on it. I understand the principle behind the catch can and it makes sense. The problem I have is that there is a lack of evidence that it actually does what it says it will do. I have no doubt it removes water and oil but does it actually reduce the carbon build up on your valves? With the amount of money involved in selling an promoting these things I can believe that someone has not performed any type of controlled scientific study. It would be simple for a company with a fleet of vehicles to take a group on new trucks and have some with and without catch cans. After a certain amount of time or mileage you look at the valves and scientifically measure the amount of carbon on the valves. I have not been able to find such a study. does anyone know of the existence of one?
Alternatively, does anyone on the forum have a GDI truck with high mileage that does not have any carbon fouling problems? How are you managing you maintenance?
I have no problems installing a catch can but I would like some actual proof that it does what it says it does.
Have a 2013 5.3L Sierra SLT with afm still on and about 210k km. I’ve been reading a lot about disabling afm and all and how it drinks oil and spark plugs get coated in some nasty soot. So today I did my spark plugs to see if there was any build up. Cause they were done about 10 months ago or longer (i think).
when I checked the old spark plugs 1 through 8 they all looked fairly the same and had absolutely no soot build up of any kind and my oil doesn’t seem to be burning.
So my question is. Should I still disable afm? Since I bought the truck 3 years ago now I haven’t had any issues (must have been built on a wedensday lol). Should I not chance it and just do it? Or leave the can of worms un opened
I got a 2018 GMC Sierra with the eassist package. I never thought of this thing as a hybrid but GMC does classify it as such. One of the digits in the VIN specifies that distinction.
I also recently picked up a Hypertech Max Energy 2 because I liked the options it provides for the AFM, specifically the speed at which it operates.
The Hypertech didn't work, says the truck is not supported. A call to their tech support confirmed that the issue was the fact that the truck is a hybrid and they do not support that.
So my question for the forum is, anyone know of a tuner that is supported on this "hybrid" pickup?
From reading sites of other tuners it doesn't look like anyone makes this distinction of hybrid. I can return the Hypertech so a trial & error approach of purchasing another tuner and seeing if it would work is possible, but time consuming and annoying.
Thanks in advance for help or suggestions.
