I am thinking about going to a larger injector, just to reduce my duty cycle and for piece of mind. I contacted a company in S.C. called Bostech and was absolutely astounded to find that not only do they not publish flow rates but they don't KNOW the flow rates. That's absurd, how can they do business? So, I'm still searching and found a set of Bosch with 550 cc rate on E-bay for $300 but that's for 8 which is pretty good. Anyone else found a good deal?
