why do people say that a 02 5.3 is faster than an 00-01 5.3?

So like someone asked. If got an HP tuner or a custom tune. It would compensate and would matter anymore right. And if the cam changed a little in the 02 and you threw in also a cam it would matter also right? Thats what I am thinking anyways.

how do you get rid of false knock? because I have a 99 5.3L

99's are known for false knock.

I dont neccesarily believe that they run better.

If you swap to an 02 PCM you should be running just like the 02 right? I mean the only reason why they might be a little more fast is becuase of the PCM am i right on this?

theyre saying its the cam also. either way, it'd be too much of a hassle and money to swap pcms and cam. might as well just buy other things
