injector size causing surging w/ long tubes on a NA 302?

I have a new (to me) theory on surging with long tubes. I'm wondering what effect the injector size has to do with the surging issue. Some people have surging, some don't. I'd like to perhaps find a more definitive answer to why than just blaming LT's. I've discussed this in more detail in this thread - http://forums.stangnet.com/showthread.php?t=402443


If you run LT's on a NA 302, please let me know what size injectors you are running, what brand LT's you have, and your experiences with surging.

Thanks,
Rick
