so say 224/224 cam with a 112 compared to a 224/224 cam with a 112+2 the 112 will have a choppy idle and higher, narrower power band and the 112+2 will not be so choppy and lower, broader power band??? did i get that right? makin sure i understand this right so i can choose my cam soon

I think that the original poster needs to clarify between LSA and ICL. When you say "on a 112", some take that to mean on a 112 LSA. Others take that to mean on a 112 ICL (as TurboBerserker appears to have done). When talking about 4 degrees of ground in advance, there is a huge difference between these two.
My assumption was that you were speaking of a 112 LSA for both cams in the original post. If that is the case, there is no reason that the 220 cam in the OP should have loped harder than the 224. Other factors must be at play (engine size, tune, exhaust, etc.).

My point was not to disagree with your opinion of the proper way to refer to a cam's specs. I was simply trying to point out that LSA and ICL are frequently confused and the OP needs to be more specific with his question if he expects to receive a definitive answer. FYI, people refer to cams by Intake Duration/Exhaust Duration, LSA, advance all the time. See post #2 below

Yeah, I agree.
LSA can't be advanced, but the ICL can. LSA is amount of the circle (in degrees) between the ICL and the ECL.
Edit (removed info that was confusing or wrong)

[QUOTE=TurboBerserker;4232111]Yeah, I agree -- I do the dur + lsa all the time too, however, anything with a xyz+a does not refer to lsa, but ICL. Your example in post#2 is not on a 111 LSA if his sig is correct, it's a 113 LSA on a 111+2 ICL.
That is an assumption on your part. Many people, including the example from my previous post, list xyz+a as their LSA+advance. Judging by the nature of the original question, I wouldn't think that the OP even knew the difference between ICL and LSA. That is why I thought it prudent to determine which he was speaking of prior to offering a definitive answer.
