new dyno numbers (lower numbers) *scans*
I went again last week just for the hell of it, and although I was pleased with the curve, my numbers were 15rwhp lower. I know dynos vary from one another, but they were both dynojets. Unfortunately the recent dyno did not list the conditions/factors nor my Air-Fuel ratio.
Anyway, is a 15rwhp difference anything to worry about? Or just chalk it up to a different dyno?
My older dyno was done when I got my LT headers and B&B exhaust installed, along with a tune.
The only thing I have done since the original dyno was add the Vararam2b.
Here is my original dyno from 2005:
Here is my latest 2008 dyno:

Any worthwhile tuner would tune a v-ram car a little more rich on the dyno since on the highway is where you are going to see the true benefit of the extra air and you simply are not going to generate that extra air flow on the dyno. Also, your first dyno was in December and then you re-dyno'd in August and are wondering why the numbers are different? I am sure the weather conditions were not the same

I always thought your 392rwhp was a little high since I had the same mods/tune and only made 380rwhp. There are a few bolt-on Z06s on here near 400rwhp and I always chalked it up dyno variances and it looks like I might be right. Your new dyno numbers are right where they 'should' be for your mods.
...Now it's time for you to do a cam swap. 50rwhp gain is 50rwhp gain, no matter what dyno you go to.

Well, it says it was 72* for your first dyno run. Any idea as to what it was for your second? I would think it would have been hotter than that in August. I honestly wouldnt worry about it. Every dyno is different and again, your tune is probably a little richer due to the v-ram.
