Smithracecraft assassin bars. And they are the new version. New version is just a 1" shorter bar. They are the number one rated bars based on my research on yellowbullet and performancetruck.com. guys all say they beat the Calvert in 60ft times. Super heavy duty.
I can't tell why I have vibration. Angles aren't too bad. Wonder if the drive shaft need shortening? I dont mine a performance shaft but wanted to rule out everything else. The shop that did alignment(twice) said 24" can't be roadforced balanced.
*Don't think the bars would fit your truck Nasty, they set 5.5" down from the front leaf bolt. and more if bars is mounted in lowest hole. *

I fought with vibrations as well. I had the driveshaft shortened and I fixed the pinion angle

Digital angle app on my phone says.
Axles is 1.9up
Driveshaft is 2.4up
Trans is 7.1 down.

We are thinking bad driveshaft. So I will have it looked at. However GM said they will give me a new replacement.
Would like the 2 piece steel but not sure it will clear the custom 3.5" exhaust.

Need to preload them but there on. Hope this weekend I can finish wiring on the 2nd amp and the door speakers.

Did you use a specific turbo kit? Im loking into them but i dont want to use headers.

On3 turbo kit is a v2 and is really great quality. V bands found be better but still work 100%. And honestly kits are cheap $2500 and up. You can buy the driver side tube header but it isn't needed no performance increase and as the crossover uses stock locations any header on that side fits.
I think the spikes kit is a little nicer. But they are $5000 and up. And company is hard to deal with. Honestly buy the bmf turbo. It's a 76 but measures 80 and is 2 times the turbo of the other options.

I heard they dont always send all of the parts with their kit so i didnt even look into them.

Also is your fuel side stock meaning pump and injectord?

Yes it is stock I have planned to upgrade as I have a set of injectors. As far as pump I can get a Corvette one, shim it or just get a cam. I was planning a new block and just build it up.

Yes they are bad about not sending parts but contact BoB at on3 and he is awesome and sent everything out so not a issue.

So seems like this solved my exhaust back pressure vs noise issue. Inserts on a turbo car/truck is very bad idea.
DENALI gauge cluster should be here this week and is a fast install. Still haven't had time to finish wiring up the amp and alpine x front door speakers.
Also working on a few new tunes. There is only about 6 shops that can really tune the new trucks. And even fewer that will or can really do a 100% job. I have spoken with GM engineers and they have poured over my tune. Saying fuel is fine and all but trans,timming, and dbw setting leave more on the table also that my palse with was to wide and the fuel ve tables would need to be completely redone once the other settings are set up. So big things in the works with that. I have two tuners reviewing and setting the logging.

Oh and bought that 9.88" 4k rear view camera. It is a front/rear dash cam with every other option. Pics coming.

So update is as follows.
Bad is the rear view camera is a Facebook scam and is shit, not as ad shows. PayPal is refunding.
GOOD finally have my Denali programmed cluster and love it. Expensive yes but it is how the truck should have came.
Plans now are the new turbo and drive out of state to dyno tune.
Again I have the better motor still brand new waiting. It's a Factory long block LT1. But truck only has 8000 miles and turbo/tune isn't finalized so rather dial in and see. Maybe a cam or injectors on the new block??.
But winter is coming and my race Camaro is past due. So need to pick a point and stop.
Oh still need the 4 channel wired and front door speakers.

So FYI running 2 way speakers in the doors sucks. In the good old days, wires are feed through door grommet now a pinned harness and multi boots are in the way. Ugh. well done just need to rewire the amp and tune it all.

Plan is a one last tune for DD and build the new motor over winter. Same time my track car is being built. Then see if the turbo truck can pull the 24' trailer and car if not Diesel tow rig? 2020 2500HD Denali.....

So I have the oil pressure issues like so many others. Starts off good 40psi at 1000rpm. Make it a mile or so and down to 20psi at 500rpms and after a few miles and getting into boost 10psi at 500rpm.

I believe it is just the super thin oil Mobil 1 0W20 dexos full synthetic. Also the 1000* turbo Can't be helping the oil temps. I will data log oil pressure vs. oil temp. After oil change back to 40psi and only drops once warmed up. odd....

I'm trying a 20% additive now. Also bought a K&N oil filter (hp-2011). Filter didn't fit, the Oil adapter for the turbo oil feed adds to the thickness and the filter hits the cross-member by about 1/4".

Trying a few new tunes friends sent me. Still want the larger turbo and dyno tune before winter...

Ive only ran amsoil in my truck. Oulchange intervals are less as well. All my vehicles use it and only that. Might givgive it a try

Yeah I looked into other oils and spoke to my buddy at gm. I'm told to run a thicker oil in the summer and to data log oil temp,pressure, and get back to them I was also given a synthetic additive. It is better than the GM data for min oil pressure for now. I believe the turbo is breaking the oil down or at least heating it up more than a factory stock engine.
I love Redline on my race engine we picked up power on the engine dyno.
Oh he said he worried about running thicker oil in Michigan winters with the the setup as now I can see 60+ pressure in warm oil.
