Edited...
I'm positive I bought quite a few things that really didn't give the results I was hoping for. Quite a few things that I really don't need at all. But I can pretty much say that everything I have I did want whether it helps or not. For instance the aluminum heads that I've been talking about, I don't know for a fact that they're going to do anyting but make my car a little bit lighter for sure LOL but I'll have fun seeing what happens if I can afford them one day...
