Lift some weights and/or do some push ups.

In *most* setups, it'll put you right around 400fps. Only in highly tuned and heavily maintained setups can it reach higher. I've seen some setups hit 440fps with this spring, but it's rare.

Different companies, different systems, different acronyms... but in the end, it's the same thing.
As a final note, it is highly recommend to also upgrade your gears to Prometheus Double Torque gears as well, to support any spring rated at M120 or higher. While motors and batteries can compensate for the lack of torque a standard ratio gear set may provide, it is not ideal as your motor will experience higher current arcs, your trigger switch will arc higher (and burn out faster), and your battery will experience higher consumption.
Depending on the severity of your setup, you may also experience overdrive, which will prematurely strip your piston.
While most users choose to skip the gears as a cost effective and short-term method of upgrading to 400fps, it will hinder the long term durability of your aeg, causing you to replace parts sooner rather than later. Such setups generally last around 1-3 years, depending on how heavy the AEG is used.
The cost of a replacement motor and piston reaches the cost of a quality set of gears (that you'll end up having to replace sooner anyways). Might as well do the upgrade right from the start.
