Message Well, as some of you may know, I've been having issues with my Z ever since I bought it. The first time I dyno'd it it was already a Stage III. All I had was 214.3 RWHP. After fixing a few boost leaks I got it dyno'd again. I pulled 254.3 RWHP. I fixed another leak I found and also replaced my spark plugs. The previous owner apparently had non-turbo plugs in it so I was bogging down past 4,800 RPM. I got it dyno'd again today with the new plugs and an oil change. I managed to pull 288.3 RWHP. I was a little disappointed that I didn't break 300 but on the way home I saw I was only boosting at 11 psi instead of my usual 14.5 psi. I heard a leak upon initial inspection but I'll have to do a test when I get the chance to locate it. Hopefully my missing 3.5 psi will put me over 300 RWHP. Here are the sheets from today. Disregard the "MAX POWER" numbers in the left corner. That is just from my automatic gear shift spikes. The actual numbers are annotated on the chart. You can tell that the first half of the runs from today and the last tiem are almost the same (today was a little higher). It is the last half when the RPM's are higher that the new plugs really made the difference.

Blue & red are from my runs on 11/26/05. Green and purple are from my runs today.

This is a chart of my time, speed, RWHP, and A/F ratio.
