Maybe a few times, but certainly not every day reliably. That is asking for HUGE problems. Where are you getting this info? More Wiseman advice from Tooners? 660's are cheap, they supply plenty of fuel for 25psi on a Big16G, and are EASY as HELL to tune with the SAFC. Any moron can tune a car on 660's on any turbo. And the best part is you avoid having to upgrade your injectors more than once. I am running a rewired 255 Walbro with 650 disc injectors and stock FPR. I am almost zeroing out my AFC settings to get even .93 o2 readings with the Green. (Not that you should be using o2's to tune anyway). 550's would have cut out years ago. I know lots of cars react differently to mods, but the extra insurance of 100cc's is worth it for the same price.
