The UFO,s are supposed to help throttle responce.I,ve never run them but if Dale says waste of time I,d tend to believe him with all the testing/tuning he,s done.

When I bought and setup my vm44, I bored it to 46mm and put the UFO in it right off the bat. There really doesn't seem to be any way to get it tuned right on the bottom end with the UFO in it. It is pig rich and lazy. I primarily just drag race the zilla, so I have tolerated it. If I had it all to do over again, I wouldn't have ever messed with the UFO. One of these days I'm going to get a new slide and start over again on tuning it.

Dale or Jerry, do you guys think the slide could be salvaged after being modified to accept a UFO? I could plug the bolt holes easy enough, but I'm afraid the cutaway would never be right.
