The alterpower is a very nice design. Not hard to install, however i been through my engine bay quite a few times. Its hard for me to tell if it works cus i installed it when i put in a supercharger, but i can tell when it works. At night when i produce a little more than 1lb boost, the lights dim. When its day time, i cant tell. I wish i could have put it in before the supercharger but oh well, now i have both.
