performance module

ok do these damn things work. cause me and my cousin disagrees. i say there are those that raise you comprasion and twek your cpm. but he says the do nothin. so does any one really know. my information came from a performance book i got. hayens i think.

There is no such thing a computer that can raise your compression. There are also no chips avalible for a 3000gt.

They don't work, all they do is waste gas.
