Gonna dyno this afternoon?!update w/dyno graph! Any tips for making sure everything is in good order with my Z? No tricks just some basic things I should do before hand? I allready have heard the drive it like it's stolen on the way there. lol Hopefully I can put up some decent numbers for a lid/exhaust 02Z. I'll post here this evening with numbers. 
Thanks.

Well I had it taken care of this afternoon. Graph #1 cuts off at about 5700 rpm's but gives me 314 rwhp and 325 rwtq. I must say with that I can be pleased with only an exhaust and lid. All the other runs I had spiked and cut out from 5000 to 5700 or so. Any idea's as to why that was happening? Tried three more runs and the same happened each time. AFR looked good as did the wonderful tq curve hitting 300 at 2500 rpms . If you look at the graph and estimate the curve without the spike I think my second run are my best numbers as it looks like 320 rwhp and 330 rwtq. So I think those will be the numbers I go with. So what's everyone else think? And please if anyone has any idea about the spikes feel free to chime in. Thanks.

Those numbers look about right. The spike is caused from the dyno's ignition pickup that connects to the spark plug wire getting a false reading at that point during the run.
