Typically...
that would be considered two and a half steps...as jets that only differ by one number could technically have been drilled with the same bit. In any event, I don't believe you would notice any change going one size. JMHO. I'm no expert. Ron

I know what you are asking hal but I don't know the answer. I am wondering the same thing and will be experimenting with that this week with the LM-1
I went to the chassis dyno this weekend and learned a few hings about my car. We jetted the pri and secs down 5 sizes and only increased the wide open afr from 11 to 12. I was trying to get to 12.5 at least. I am going to try and restrict the power valve circuit to get the rest. If you think about it, the whole power valve is theoretically worth about 8 -10 jet sizes since they stagger jet the carb about that much to account for it. That may not really work out that way if you actually checked it out on the wideband. I'll let you know what I figure out when I figure it out
