You need to check the pressure at the rail, because you are DIYing electronic fuel injection. You have changed a whole bunch of stuff and need to: 1, verify that it's working like it should, and 2,...

https://www.rockauto.com/en/moreinfo.php?pk=8785812 - includes a bunch of crap you will never ever use for anything, but, I'm not aware of a cheaper kit that has only the parts you need.
No liquid filled. No permanently mounted on the rail. Needs to have a hose long enough you can put it somewhere you can see it from the driver's seat. It's supposed to be a diagnostic tool, not...
That does not make it a 'return style' system - Corvette filter/regulator functions exactly the same as if the regulator was built into the sending unit inside the tank on a returnless system.

'TBSS intake' is as bad as 'my Denali'.
Nah dude, it's MAF-only, it doesn't even use VE.

The results with Google mostly lead to, let's just say, unsavory sources.

How much pipe is there after the O2s? If they are too close to open air they will be false lean. And I sure hope there is at least one wideband being used somewhere in a setup like this and that it's...
Fuelab. None of the others I talked to could even understand why holding key-off pressure with EFI could possibly be a good thing, and all claimed that making it leak when the pump shuts off somehow...
Yes, it holds key-off pressure. Will it hold up long-term without a real hardened & ground seat/pintle? Don't know, I will retrofit it with an insert if it fails. All the other brands dismiss holding...
12614311 means it came off a 2010-up LMG or LC9, which was never used in TBSS. I only mention this little bit of annoying semantics because you injector data is way off from anything GM ever put in...

There is no 'Knock Retard' PID in your channels list; you can't chart or graph a thing if its channel isn't in the main list.
No, you shouldn't bolt down a rocker while the cam lobe is up, even if it's one single rocker by itself. With all the rockers on a common shaft it's not possible to bolt it down when zero valves are...
The thing I don't like about 1-piece-shafts is, there's always gonna be at least one valve on each bank way far open no matter where you put the crank/cam. Depending on your springs pulling the shaft...
That's not a current valid GM part number, though some sites list them as crossing to 12580426/88894361. Where did they come from?
Here's the correct injector data, assuming "flex fuel denso injectors" means L59 (12580426), and that "lq9 rails and regulator" means it's referenced & 58 PSI base pressure.

If you're returnless/non-referenced and at 58psi, then the injector data is as it should be.
If the data you found for scaling the injectors said "these injectors in this PCM do not need to be scaled at all, anywhere, for any reason" then yes, that'd be correct.
Since DW doesn't have...
The ECM has to be powered up and awake before you can scan it or read the tune out. If the ECM isn't turned on when the ignition is on, and you do a 'read' with HP Tuners and save the file, the ECM...
Without the log files showing it doing the thing in the cool story and the tune file being used when the logs were recorded, the cool story all by itself is going to get you nowhere.
The BTR shafts are real 52100 steel the same as real bearing races are made of (and same as Jesel/T&D would use), not 4140 like nearly all of the needle bearing trunnion kits. It's not possible to...
All the other information is needed. Like fuel system/regulator type, and intended use (daily driver low boost, weekend toy, dedicated balls-out max boost race?), and injector dimensions (length?).
