If you want to spin past 6000 rpm at 16-17+ psi constantly, they wouldn't be a bad idea. That's where the fuel supply starts to go bye, bye (lean) for the stock injectors since they go static (100% open) at about 5500 rpm. For the occasional blip past 6k in 1st, 2nd and 3rd, less of a need for the bigger injectors.

Wait until you get it all together, then decide if you need the injectors. sad but true unless you have turbo you might not make all the boot you really think you are making. Never trust the MFA
