I wouldn't say that's true from what I've seen but it surely seems probable.

The way around this is with precision, mentioned in first post. Always spraying at high pressure ensures that the alky/water mixture is always fully atomized. Then, making sure you have your injection point a ways upstream from the throttle body will ensure that it mixes evenly with the air flowing into the engine. If its fully and evenly distributed in all of the air going in, it should go to all cylinders equally.

If you use a PPS kit and it doesn't always spray at full pressure, then yea, you can surely get alky in some cylinders and not others, especially right when the pump kicks on...which incidentally is right during boost onset and then peak torque...see how that could lead to the pics mike posted? Yup.
