Hey, I've got a 2019 Silverado with the 6.2L. I want to upgrade the throttle body and intake manifold for some more horsepowers. Has anyone done this on there 6.2? All i am seeing online is throwing the 6.2 manifold on a 5.3. Thanks in advance.

Good Afternoon fellow 6.2L enthusiasts. I apologize if this sounds like a commercial or a rant. I just like to share what I've experienced and discovered. So, I don't know about you, but I've been searching for a way to cram more air into my L86 that won't break the bank. I've done hours upon hours looking for the perfect bolt on's or practices that will help the block breath deeper. I've learned that swapping intake manifolds are not worth it however, porting makes it one bad ass manifold. (which i've done) I threw on an AFE CAI and that really helped get the air moving. (momentum GT pro 5R) Headers and a bigger full exhaust helps get the flow rolling. (I'm rocking TSP 1 7/8 Headers with a 3.5" full exhaust (catted with Cal Cats) and a Flowmaster Pro series Muffler) Cylinder Heads and a Cam shaft will transform your truck. (going with TSP Heads and a Trick Performance Cam package) And a basic tune wakes these bad boys up. (local dyno-tuner) That being said after the above you're looking anywhere between 430-530 HP N/A. Obviously the Cam specs are going to swing that number. Now, The one thing that I have NOT been able to find is a Larger Throttle body that will fit the L86 Stock Manifold. So I did what most have done and ported that sucker out. The only issue is it will never be larger than 87mm. Until this came along. https://www.bbkperformance.com/92mm-throttle-body-14-18-corvette-camaro-lt1.html FYI slight modification is required to the stock Manifold. You need to shave the base of the Vacuum port as well as the MAP sensor base for the frame to fit. Once that is done you're rocking. I was able to Port match the TB Bore to the manifold inlet and smooth out the transition. Honestly I can immediately feel the difference. When I get a little bandwidth I will throw on some videos of Cold/warm starts, take offs etc. If you have any questions feel free to reach out!

2011 silverado first started shifting hard into first gear. Next issue started idling at 2000 rpms. Replaced throttle body off my 2008 Tahoe problem appeared to go away. Purchased used throttle body and installed relearned computer idle intermittently went high then normal. Hard shift went away until recently now throwing error code for trans and shifting into neutral. The problems seem to be intermittent and different issues not same one constantly. Been working on this going on about a week. Does anybody know or has had any related issues or a direction to go now would appreciate any help. Wanted to possibly reset pcm since it seems to be a computer related issue.
