Very unlikely that the injectors are anywhere near maxed out with gasoline, especially on a flex fuel vehicle. To safely run e85, you need more fuel per unit air, much more than would be required by standard intake/exhaust mods. Therefore it is a lot more likely that if indeed there is a lean condition it is ecu limited, not injector limited.

Has anyone put a gauge on the low pressure pump, high pressure pump, or at the rail?

The fuel rail has a pressure sensor. You should be able to read fuel pressure through a scan tool. At least that's how it is on the ST, and I can monitor fuel pressure with the torque app on my phone

yes, but if the rail is dry? is it starving from the low pressure pump? Or because the high pressure pump can't keep up with the injectors?

True. It would be nice to be able to monitor all 3 spots at once. I am curious to see what the flow rate of Tue stock low pressure pumps is, and how much over stock they can handle.

From a tuning standpoint knowing what's happening at the rail is great. Beyond that, you don't know how much you can grow without testing the entire system. Until now, I don't think there has been any reason to find out.

I wouldn't touch that thing since you have no idea what it is changing, and the fact that it says it can be used on multiple cars I doubt it does anything. Wait for something that is made for the mk3 to come out to know what you are buying
