LOL....

 

i have a k03s apparently...and i also have a k04 sitting in my garage how much of a difference and im going to notice...just hold my boost longer?

 

You will get a slightly higher spike and hold boost all of a couple hundred rpms longer. Not much of a power or powerband increase. They are rated 5hp differnt and people still dont get that pushing on the same as the other will net basically the same results
