I'm just about to order some injectors but I've been swaying back and forth on which size to get. Initially, I was just going to go for the extremepsi ball style 550's but I'll be getting a 50 trim PTE turbo sometime in the near future so the 550's won't be enough. Also, being in california with crappy 91 octane and wanting to run as much power on pump gas as possible, I thought I'd go with ball style 680cc injectors. Should I go bigger like 730cc since they are the same price? Will the S-AFC be able to compensate for these injectors? I know it only has a +/- 50% range...

My supporting mods are currently:
Autometer boost gauge
Autometer AFR gauge
Free mods (hacked MAF, no boost solenoid, larger vacume lines)
MBC
3" turbo back RnR exhaust
2G ported manifold with EGT's
Aquamist system 1s with single 8mm nozzle
255lph fuel pump
20x7.5x3.5 spearco FMIC and HKS SSQ BOV (yet to be pipedLOL

Thanks! :)
