Yup I have 740's on stock twins, Like I said, I dont plan on keeping the stock turbo's. Why spend more money on a bigger injector down the road? I did the mods I did with the thought of how the car will be. the 740's work well with stock turbo's. My airfuel with a JWT ECU is a 11.3-11.8 under boost and the duty cylce is 53%. The car also starts right the hell up, dosnt have a rough idle by any means. I like the fact I don't max out my injector and it runs smooth.
