I know this because I have used Bosch 30lb hi-imp injectors in these motors with a special chip I created.
The DME has no issue firing hi-imp injectors but it must be properly programed for the given injector spec.

But Sal, I've been on hi-imp injectors for years and they perform better than the originals on a stock chip. Just goes to show that there are some experts out there that seem to have more experience than we do. Meanwhile, if and when find the downside I will certainly let you know. Aside from chips and injectors, the real performance problem with the 3.2 is the lack of expertise in air flow meter adjustments and there are just as many ways to make it worse as there are there are to make it better. Knowing how to properly set it up far out weighs any benefits from injector or chip mods if AFM outputs garbage in then what you can expect is nothing more. This is why not all cars will benefit equally from a chip or injector mods.
