The more people blow black smoke, the more motivated tree huggers get in passing laws against those kinds of things. If you are set on turning of the IP, the others already covered what you have to do. Get a pyro and read on how to turn your IP up. I would start by turning it up 1/6 turn and then if your EGT's are fine do another 1/6 turn. You don't want to turn it up too much without a turbo.
