Assuming LLX3 ECM and CDANM4 strategy, here are the stock spark tables. The lowest spark value for a given RPM and Load point are selected among the three tables. Then this value is modified using inputs such as ECT retard, ACT retard, KR retard/adder, IMRC adder, etc.
Three tests that can help you definitively determine if there is a blown head gasket and/or locate the cause of your issue: cooling system pressure test, engine block test and/or leak-down test. These will give you much more useful information than a compression test.
I know this is not the proper place to post this, but since they're only applicable to 94'-98' SN95s it seems apt. I found this listing on OfferUp for anyone looking for a set. Looks to be actual SVO skirts and decent condition too! No matching Borla exhaust though.

KOEO = Key On, Engine Off. You can try to depress the schrader valve on the fuel rail shortly after doing so. If no fuel spurts out, then you've more than likely found your issue. But a fuel system pressure test is recommended rather than throwing random guesses and parts at the car.

Do you have before and after dyno sheets? I'm interested in the mid-rpm gains with that setup. Did you pulley the T-Trim for max blower rpm with the wastegate?
If you can, pressure test the fuel system at the schrader valve (fuel rail). Sounds like a fuel pump issue to me. Can you hear the fuel pump prime when during KOEO?
How's the fitment w/ your car since it's turbo? I'm leaning towards one for my 96' but was wondering about fitment issues with forward facing turbo kits.
Agreed with the above posts.
Also we don't know the setup (6-rib vs 8-rib) nor how much timing is added between each run. If timing on the latest run is lower than the previous runs to save the shortblock, then that's understandable.
Are you sure you're not getting belt slip? 6-rib, 8-rib...
Hey guys, I pulled these part numbers from some old threads a couple years ago. I've not been able to verify them though. This also does not include spaces/shim sizes that could be possible needed.

Well considering the SI-Trim flows 50cfm less than a T-Trim, I would also look at T-Trim numbers for comparison as well. That should get you more data to compare. But I'm curious to this as well too.
