Hx35 and gears

Alright thanks. As you know I have been looking into y'all's injectors for my Svo. I know that for the power I want to make (around 400rwhp) in need the over 80lb injectors (can't remember the exact sizes off the top of my head). With a Pimp to control this size of injector will I have issues with the car loading up at idle or will I be able to pull enough fuel out? This car is daily driven as I mentioned and I want to know what I am getting myself into as far a driveability goes. I know it won't be as good as stock due to a bigger cam so I'm not worried about the compromise I will have to make. I just want to know how much of a pain, if any, it will be to drive. Other than the fact that high impedence injectors are easier on the ecu, are there any other benefits to running high impedence injectors? Correct me if I'm wrong, but wouldn't low z injectors perform better at idle as the ecu would have more "control" over them due to the lower z?

Modern high z injectors perform better overall than low z.

There is no limit to how much fuel you can pull. You can pull so much that it gets no fuel at all if you want. Huge injectors and loading up at idle is related to physical limitations of the injector (how long it takes to open) vs the amount of pulse width the engine needs at idle for proper AFR.

This is one of the reasons we offer a sequential version of our ECU and point people towards it when they want to run injectors over 80lbs. With that said, you've got to get much larger than 80lbs (if it's a good injector) before you have issues with it running "bad" at idle. There is just a lot of space between running "bad" and running "perfect".
