New dyno numbers...
After borrowing max's stock turbo so that it wasn't pissing oil all in my intake manifold, and installing the profec to keep boost steady, I now have a good baseline dyno from Coastal.
I was trying to get a baseline a/f on 15psi, but my car was pulling timing VERY hard after 4krpm, so it was either just to hot outside or as brought up to me by a friend, it could've been mechanical knock at some point. So I left her at 13, the same boost as my original baseline.
I still really want to hit up SS for a Dynojet baseline, however since both their shop and myself are always busy, I have to stick to what I can do on my lunch hour.
New numbers: 206.2rwhp@5050rpm, 248rwtq@4350rpm.
The boost still dropped off after 5krpm for some reason, but the car makes peak around 5200 anyhow, so it wasn't a huge loss. I've got to play around with it some to get everything right.
A/F ratio was a rich 11.8 until 5krpm where it was at a nice 12.2.
Im estimating a 12% difference after talking with someone who has done a dyno on both an MD, and a DJ. He had similar losses.
EDIT: Not bad for $700 including the cost of the car.

goood numbers. When I had the t25, it did the same thing with the boost creep. I don't think those turbos can hold a consistent 15 lbs. It kept doing it but it was still a great turbo with no failures .
