Phillip Long 2 step rev limiter question

I just got finished installing the Phillip Long 2 step rev limiter today.

I dunno... but it doesnt stutter as fast as I thought it would.

I adjusted the little calibration knob and the fastest it will stutter is about every half second.

Is this the way his rev limiter is designed?

most of the rev limiters I hear at the track stutter about 4 times a second.

it works fine and builds boost at a stop but it kinda sounds funny. it doesnt really sound like I have a 2 step. it sounds more like im pressing the throttle up and down as fast as I can.

for those of you that have it installed...
is this the fastest it will stutter?
