How do you figure this? With a six speed you control how high the rpms will be.

 

so people are seeing gains with a pop charger? or is this just for the sound?

 

^ The pop charger doesnt show much for gains you'll be lucky to get a few whp at most, The sound though is nice and aggressive. Most people go with it for the sound. I think theres a vendor on here selling them at like 95$ plus shipping. I know some people were getting them for about 110 or so shipped
