This is exactly what I've been looking for, thank you so much for figuring it out!!! Please let us know what the results are.
How much compression is the engine? How big is big for your cam? Pump gas only or you gonna run meth?
Could you start the dyno as low as possible. I know this doesn't matter to many people (if any). But it's my main reason for FI (max power around 2000rpm) and I really wanted to know if this big of a compressor (on a 5.3) falls off hard towards idle.
Thank you very much for all your help, I can't wait to see what it puts down. Where do you think it will end up to the wheels, Do you think you'll see 500/500?

I don't think I've ever seen a dyno start below 2000rpm. I was hoping you'd get as close to it as possible. It's discouraging when someone post a combo has "great low end power" and then you see their dyno start out at 4000rpm.
The pics are great, thanks. Can't wait to see the results!

Sorry fellas, no dyno results anytime soon. Had to tune on the road as there was something torn apart in the dyno bay. What I can tell you is that I am only hitting 6psi which isn't really a big surprise but I am able to run 20+ degrees timing in 100* ambient with no knock retard. I am ordering a smaller pulley tomorrow. Possibly track times next week if I get a pulley soon enough
