Went out for some logs and realized that I have had my wideband calibration wrong the whole time I have worked on this project... I reset for the correct AEM cal and did some fueling work, it was actually pretty close before I futzed with it.
I did get one 5th gear pull though. I think the power spike in the previous graph was an artifact from hitting a bump doing a 3rd gear pull. The 5th gear looks a lot more... plausible.
I felt like the car was a little down on power, so I hit the drag strip. Naturally I broke a couple small things, but the engine has been flawless. What think? Down on power for 19 psi on a .86 a/r gt2860?
Power? No you're not down on power. 113 trap for 280 is actually good IMO
You're definitely down on spool and lowend, and 19psi is kinda high boost for only 280, but you already knew that. What's the spark map look like? or post a pic of log showing timing curve. Maybe you're really low on timing

I'll post the log from the last run. I think in 5th it was 12 tapering to 13.6º advance when I let out of it. I added a degree to the top two rows from this map.
You've a built engine, unless you're pinging/knocking with more timing, that's way too low and you need to crank that baby up to at least get some of your torque back

I'm gonna do just that, but only when I can get on the dyno. Apparently my dyno guy has a bad graphics card or something on the dyno computer. I'm still considering a different turbo, like a gtx2860. I want my spool back...
I'd just get the most out of this setup as is if I were you. If you're spending 1200+ on a turbo replacement might as well sell this setup and go TSE mani + 6758efr and make like 400 on this same map and boost level

Does getting the most of this include swapping to a .64 housing? It's not really fun on the street, 2nd gear doesn't make real power until 5k
It sounds like you want us to tell you to keep polishing this turdy setup and get the .64 housing lol
...so do it and crank it up
(but secretly we will all be hoping you'll finally see the light and go EFR )
I'd love to, but spending that much isn't sonething I can do right now. Selling this turbo and buying a .64 gtx2860 or so with the current hot side is doable though. I'm just a bit unsure as to why this turbo seems maxed at 300 when it should make way more.
