Strengths: Good control, no spikes. Easy to install and operate.
Weaknesses: Single boost setting. $Price$ - You could probably find a used electronic contoller for a few more bucks.
Summary: This is the upgraded version of their standard boost controller. Still bleeding technology however this is more accurate with it's ball and spring mechanism.
I am happy with this. I am using an internal wastegate (more prone to spikes) and do not spike at all with this controller.
