big 16g and am wondering should I go with 660's or stay with 550's

I plan on getting a big 16g and am wondering should I go with 660's or stay with 550's. What problems would I have with the bigger injectors? Thank You Winter

What are your goals?

What are you going to use to control fuel?

 

[winterftbl]

Goals are right around 320 to the crank. And was planning on buying a safc1 and datalogger.

550's should be fine. The money could be better spent on a better tuning seutp.

550s will be fine, but id go with 660s just in case you wanna upgrade more later. Also look into get the dsm chips chip burned for 660s and such. He messes with the timing a little and also it has fun extras like a 2 step.

I'd do your homework with a 660/SAFC setup. If you can promise us that 320hp is your limit, 550/SAFC will certainly get you there. When you go to 660s you may end up with too much timing advance from the SAFC and have knock issues. If there's a strong chance you'll get all hp happy, the 660s will give you plenty of growing room, and you could go with an EPROM ECU+chip, DSMlink, etc.
