L86 - 6.2L Intake manifold installed on 2019 Silverado with L84 5.3

Hey guys-  Just wanted to share that i have my manifold combo up on ebay. It also includes the elite catch can. I think the starting price is super low for what it is. if the buyer is in Utah, i'd be happy to include the cut airbox and the 6.2L duct for no additional charge. (if picked up)

I just did this mod on my 2020 silverado trail boss and the truck is throwing 2 codes. P0171 and P0174. Looks like the engine is running lean. I have a corsa cold air intake and an AFE muffler. Looks like I'll be putting the old 5.3 intake back on till someone can come out with a reasonably priced tuner.

assuming there is an air leak then. I'd recheck everything first

There was a hairline crack in the side of the manifold causing a vacuum leak which made it run lean.

Hey guys - did the stock PCV lines on the L84 line up with the L86 intake manifold or are any different ones needed?
