What are your system specs...maybe I can help?

It's a self extracting archive...you have to install it first. Just click through the self extracter and then you can find the program on your C: drive and run it.

Unless you are running Windows 3.11 or 95???

Ok, I'm setting everything up for a run.

What are the sizes of your intake and exhaust valves?

What kind of CFM induction do you think you have?
