There are endless answers to this question with a quick search. Still, Ill answer with a little less analysis.

If the water pump isn't at the local lost & found then it's really a toss up. OK sorry terrible joke, but this is one of my favorite DTC's of all time. As if a water pump just randomly goes missing...

Absolutely. To answer your other questions. Yes, data-logs would be helpful here. However, any stored DTC's would be great.

Sounds like you found the flaws in changing too many things at once. Really hard to say what's causing the issues.

What's your spark plug setup? Logs? Tuning? Other mods? Actual 19T turbos like...

The above is a solid article, and there are a few other blogs with detailed posts on N54 issues.

I'd say outside of what's listed above a few other areas that can be problematic include:

Between slow spool, no boost, black soot, rattle, and white smoke it sounds like your turbos are done. Hard to say for sure without seeing/hearing the car in person or more data, though.

How do...

Yeah go 6466 IMO. As Ruski stated you really won't notice much difference, if any. All else equal including tuning, the 6466 will take some extra RPMs to spool. However, it's a small difference and...

Did you just recently upgrade turbos? When you say you have the JB4 bypassed you mean you're running the car on map 4? Is there also a back-end flash or any custom flash?

I personally really like DI only apart from the carbon build-up issues. Regardless, I went with PI partly because I don't trust the HPFP overdrives but mostly because PI is proven. Port injection...

If you want to ensure some stuff is good for the longer run while also having some fun I'd mix in some mods alongside a bit more preventative maintenance. If Cobb and FMIC are your only two mods I'd...

Valid point. RB GF's will deliver a lot of power without needing too much torque. Of course, the torque is going to come in faster and harder on the twins and that is tougher on the engine, clutch,...

HPFP and LPFP pressures look fine. HPFP is pretty high; probably working hard to try to deliver more since you're leaning out and fuel trims are pinning to 50.

Bad O2 sensor(s) can cause issues...

I'm not sure if I simply can't see it for whatever reason, but there's a lot of valuable data missing from these logs. Where are AFR's, HPFP values, etc?

Looks pretty normal to me. You don't have any timing pulls in either log that I can see so you might be able to get away with a bit more timing. Especially if you're only running 19-21psi on TD04...

Looks solid. Keep logging on occasion and pay attention to the HFPF pressure. You had a pretty severe drop to about 900-1050psi (6-7 on log) in the mid-range just past 5k rpms. You didn't lean out at...
