No - installing the ULE trigger kit in an E-Mag can actually slow it down, as it reduces the reactivity of the valve and doesn't have as much 'push' on the on/off pin, so the solenoid doesn't reset quite as fast.
I'd avoid putting it into a classic valved mag as well, as it makes them a lot easier to short-stroke.
The ULE trigger works best in mechanical mags with a RT/X type valve (needs to be one with two o-rings at the top of the on/off hole).
