Need Advice about larger Injectors

[TURFNNSURF]

If you check my Mod list, I have everything and more to complete stage 1 for 300HP. I have a rewired 2G MAF waiting to be installed plus an SAFCII on the way. I know there is more power waiting to be let loose with Tuning. My question is this: Should I buy 550, 650 or 780cc injectors to complete my setup for now?? Extreme PSI has some pretty good deals on Injectors on Ebay. I just wnat a little imput from DSM'ers that have "been there, done that" and would do it differently. Basically I don't want to buy 550's, if i use bigger and tune them down till I get a larger Turbo..

Thanks in advance for your help....

I'd go 650's, it doesn't take much to max out 550's.

I would go for 650cc injectors. Anything higher and I would think you might run into trouble tuning with the S-AFCII. Really big injectors ( past 650cc's ) have trouble working right b/c all the S-AFC is doing is leaning out the MAF signal, not actually compensating for the larger injectors which would need a longer dead-time between firing especially at idle.

would 650's be ok to run on the stock turbo on a SAFC II? or would it be better to go with 550s? thanks

Your forgeting that your 2G MAS will also help you to lean stuff out. So I would suggest the 650's
