I've been working on tuning this MSPNP1 on my 97 for about a year now, completed my turbo just a few months ago in the summer, and i've been trawling and digging for every bit of information I can find to make it easier. What i've got now is a "safe" (Actually just super rich, retarded, braindead stupid) tune on a T3/T4, netting me about 12-13 psi without any sort of boost control.
( tiny useless intercooler, ~440 ish CC injectors, stock coilpacks )

Until yesterday, i've been running my base map's default advance tables, slightly adjusted in cruise pressure, and noticed two things.
a) there's no power whatsoever in the top end. It feels like it makes less power at 12psi than at 5.
b) these numbers are mad retarded.

Now i've adjusted them upward a tad, but i'm hesitant to go further because I don't currently have detcans, and this is my first time touching ignition.
I'm uploading my msq and a short datalog I made of an acceleration run just now after advancing the boost cells about 5 degrees, and noticed much improvement, but before I go any further I'd appreciate a quick once-over from a trained eye, who might spot some glaring issues I'm totally oblivious to. No sense tuning around a completely fucked base setting, right?

TL;DR: Please sanity-check my tune before I continue running with the stick.
Thanks a ton for any insight / bashing you can offer. I really need the kick in the head right now.

attachments don't work (god knows until when...) so better upload files somewhere and link (dropbox, mega, g.drive..)

well here's the log , and here's the MSQ for it.
Thanks again!

3-week bump, any direction at all would be appreciated.

Main thing that jumps out is that acceleration enrichment is triggering too easily - try a higher MAPdot threshold.

The default MSPNP maps were cautious under boost, but only the dyno knows for sure.

thanks Matt, i'll give that a try next time I go for a drive and will report back

To properly tune spark you need a way of measuring torque so that you can determine where MBT is. Generally this is a dyno, although some people have made it work wth virtual dyno. It needs to be extremely consistent, though.
