Here is my dyno graph with STD correction and smoothing of 4. Ambient temp was 71 Fahrenheit with humidity around the 40% range:
This was with a stock bottom end on 25 PSI of boost on E85 fuel. My 870cc injectors were at 100% duty cycle and I'm sure the walbro 255 was nearing its limit also...

I tried uploading a larger image from my photobucket but the forum website won't let me do it.
Here is a link to the image instead:

I didn't build this one, I bought it from a fiend that had it under a tree for about 8 months after he bought and had it tuned.
I have almost all the information, any questions just ask.
