Ecu editor or PC5?

ECU editor if you have someone that know what they're doing. Otherwise, PCV
 
Use ecu editor to remove limiters, raise rpm and if the tuner knows how to use ECU editor then you will not need a power commander. If your tuner likes the power commander then that's what you might have to use.
 
Thanks for the replies. I have a tuner by me it's WIN racing in Naperville. He supposed to be really good with an Ecu editor
