First off if I'm running Autronic PNP do i need High or low impedence for best tuning ability or doesn't it matter?

Second all the sites list the sard injectors (540cc, 650cc, 800cc) as only suitable for Version I - IV (up to 98) except Greenline that lists the 850cc for version V - VI. My question is are any of you running sard injectors in a 99 with standard fuel rail and what size are yours? For what I'm aiming to get at the wheels 850cc is overkill...

Cheers
