I have a Anderson Power Pipe that I bought in November,I haven't installed it yet.
In most cases that I've seen,most cars when they add the Powerpipe,they generally see an increase of at least 1-2pounds of boost.Either way you look at it,it's still a nice add-on,because you are bringing in more cool air for the blower to work with
What kinda blower do you have?
