Couple updates. The turbo won't boost past spring pressure because there's a pig sqealing under the hood. Tomorrow, I'm hoping to get out there and track it down. The tuner says it sounds alot like a coupler for the piping. Hopefully it's just that. Maf scaling was erratic so that had to be completely rescaled. Some adjustments in the advanced timing brought the surge even more under control so it's even less noticeable. Boost is all over the place but not over 15psi because of the leak.
We are remaining completely knock free, though.
We've switched over to open source tuning since windows 7 was causing erratic readings with the v1 streettuner software. We might go back to the streettuner eventually. Hopefully I'll have some logs to post pretty soon. No point in posting anything now.
