I think that's why although most (non nismo) Z's come in around 273ish +/-5 SAE corrected on a dynojet, but every now and then, one comes in on a dynojet well below the low end of that -- I think it's gotta be an early dyno run before break in is complete.
After 5K, a low baseline (say, below 268 on a dynojet) would make me think the compression should be checked or an overly conservative correction factor is being used.
