Stage 2 LPFP - worth it?

In reading about HPFP upgrades, I'm finding the Fuel-it LPFP which states that you can run pure E85. Is the stage 2 LPFP worth it? The HPFP looks very expensive and painful to install, so wondering if the LPFP helps enough to a noticeable power bump? Or does running the LPFP require port injection or something else? Sorry - a hint confused about benefits vs cost.

Thanks all!

What is your current setup, and do you have any future mods planned?

There's no need to do a lpfp without first doing the hpfp, with the exception of running port injection.

Fueling is relative to modding, and tune. If you aren't running to boost levels that require additional fueling or alternate fuel, why would you change the FP? Are you running a tune and scanning and running lean? Do you understand what I'm asking? Just putting in a pump that "can" provide more fuel doesn't mean squat if not being used for the right reason and the engine being told what to do with it (tune).

Good Luck!

You really don't need a LPFP, because a good HPFP can do more and is easier to tune.

Talk to Bob @Stage FP in NC - he did my tune, and is a fantastic tuner.
