2016 Chevy Silverado LTZ Z71

I took off the ported intake manifold tonight........I was fighting with a "lean bank" engine code and think all the added airflow was causing a lean condition
I also felt that the truck did great at higher RPM and I lost some low end grunt
After disconnecting the neg battery cable and swapping the manifolds, I feel that I have all the power back
I will post the manifold up to sell............likely best to run it on a custom tuned 5.3L
The funds will hopefully go towards tires

Ended up switching my 19 from 275/60R20 to a 285/70R17.

I highly recommend you look into this. It could mean the vacuum pump has failed or is failing. These new ecotec motors don’t pull enough vacuum off the brake booster at idle or in 4cyl mode so it has an accessory pump. It is lubricated directly from engine oil and failure of the pump can take out the booster as well as spread particulate into the engine oil.
Mine went out a few yrs ago and fortunately everything else was fine. Giant PITA to change.

I will say that I was very hesitant about the capability of this truck in the snow
However, with some recent snow storms, I have been very impressed
I never had to use 4HI / 4LO and just merely ran the truck in the 4WD AUTO
Did not have any issues at all, even in some very deep drifts

I love it. I still haven't gotten around to sending in the files for a custom tune. I wanted to try the canned 91 octane tune first. Been kind of distracted lately with buying a GFC camper for it.
And yes, 4WD auto in the snow is really good. I flog this truck pretty regularly, and the whole system works as it should. I will probably be upgrading the cooling system at some point, as 4WD low and desert mountain climbs seem to push it to it's limits. Thinking of starting with a bigger fan.

Did GFC have a top to fit? I like their products, just disappointed in the domestic products. I saw one on a Dodge and found it was a one off.
Did you get it yet? Delivery or pickup?

I just confirmed the build last week, so I'll probably pick it up in april/ may. I think they started by making tacoma caps, but they make just about everything now. GFC forums has tons of info and pics. I'm actually getting the V2, which is a big upgrade from the V1. It was nerve racking putting that much down on a cap unseen, but I'm pretty excited. I've seen them in the wild here in CA, and they are pretty sweet.

I have been to the plant and they build a quality product. They are just up the road 125 miles from here. Popular recreational area. Real craftsman. Something to last a long time.
