Yep, it was in the Direct Connection Test Car. RPM was kept under 7000. If I remember right the shift light was set in the mid 6000s, but I was not driving it at the time.

It was 440ci, aluminum block, all aftermarket forged bottom end, apache heads, 6.1 intake mounted backwards, custom grind cam, 88mm Turbonetics, ice water intercooled, and so on.

To be honest we did not intend to run boost levels quite that high at first, the tuneup was not ready for it, and we did saw the plugs off at that point. Hopefully we can get back to work on it, reduce the boost a bit and sneak up on it...rather than hitting it that hard right out of the gate again.
