Since I had my motor built and installed by Thunder Racing, I had some dyno numbers from their dyno. Since my car was at LG for the cage install, we (myself, Jason @ Thunder, and Louis @ LG) thought it'd be kinda cool to dyno my car at LG to see what an actual difference may be. Honestly, I thought LG's dyno would read high. I was a bit surprised by the results.

I watched them Dyno / LS1Edit tune a bolt-on 02 Z28 just before my car went on the Dyno. They got 349 RWHP out of it (baseline 341, +8 from tuning). Nice results. His car came off, my car went on, there was virtually no time in between for them to mess with anything, so I have no reason to doubt the results.

Now, for a bit of history. My numbers are noticeably low for a solid roller motor. That's fine - we know the heads were kinda goofed, and that's why I've got a brand new set of GTP Stage II LS6's sitting at Thunder Racing right now (heh heh heh). They go on in October. Anyhow, that's another story, this is about two dynos.

For a summary, my car dyno'd 442 / 394 at Thunder on its best pull. Most pulls were high 43x rwhp. At LG, the best pull was 434 / 389. To me, that's 'round off error' that can be attributed to almost anything. So, in my opinion, the two dynos read very close. :)
