I am going to install a boost controller tomorrow, but I wondering what is the best way to install it. I know that it should go in between the wastegate and the positive side of hte turbo, but what is the best method to install it? Do you install it from the top side ofhte car or by going underneath the car? I can't seem to get to it very well from under the car. Also, there are a bunch of hoses from the top side. Do I have to remove my intake pipe to install it? Anyone done it before? Thanks,
