Well, that is one of the reason you frequently find the BIG flow injectors (say for racing) are of the Peak and Hold type.  Using a large flow saturation type would be a bear to get a good idle.  I happen to use the peak and hold Mazda injectors myself and have no problem with idle.

 

Somebody take away Rusty's motorcycle helmet.

According to MSD the Satuation types take approx 2 milliseconds to open whereas the Peak and hold only take 1.5 milliseconds. 

 

I've always wondered if this wasn't the key to why some people get better idle than others.  I recently changed my primaries from 550 Saturation type, to 460 saturation type, and didn't see any difference in idle.  I wonder if a set of 460 peak and hold injectors, with a minimal size resistor (more punch, but still within the driver's current limit) wouldn't work better.
