Video of my air fuel ratio using KL injectors.

Video description says it all.

Also I AM NOT RACING or even going the speed limit, this is just to show how a boosted ze will behave at 5 psi with stock KL inkectors(not k8)

You're only running 5psi, stock injectors can handle that. And running an FMU essentially just jacks up your fuel pressure to levels beyond where the injectors should be. Stock injectors aren't recommended for a boosted setup because it gives no room for expansion. 5psi isn't much boost.

I also don't recommend over 9psi on MilleniaS injectors. Not saying I haven't done it, I pushed 14psi on mine, but the fuel pressure was jacked up well beyond safe ranges.

Running stock injectors on an FMU is stepping back into the mid to late nineties technology for boosting KLs. The car will still run, but your tuning capacity is next to zero and you'll go slower and make less power. Another thing to look at if you raise your boost is the stock timing. Stock timing is a little aggressive for 5psi, but for 10-15psi it becomes plain careless. I believe stock timing is about 29-30 degrees up top, past 18-20 you'll start seeing detonation and gradually kill your motor on any real level of boost.

So in short, running 5psi on stock injectors only proves a lack of knowledge or proper budget.

Yup, lack of budget. Its way faster than a stock ze, and well i just dont have the time. Just wanted to post video as there are people who say its impossible. That its crazy.
