help me

[2006 grandprix]

I have a 2006 grand prix base model. I have an 2.5 downpipe, exhaust, spark plugs, 180 thermostat, hv III. I was told I need a new pcm before I do this, but all the pcm's I find are for the gt's and up with the superchargers, since I don't have a supercharger I shouldn't have the computer that is suppossed to recognize it. Does anyone know where I can find a pcm that is programmed with a supercharger in mind. I also really want a wizair, but I can't put it on because it hasn' been made yet for my year. Could anyone tell me a comparable or better intake system to buy. Thanks for the help. Also looking for rear bumer from 2004+ grand prix gt or higher(dual exhaust cutouts).

Making your own intake that puts a 9" cone filter in the fender-well is the best bang for the buck. You can use flexible tubing like Intense sells and get pretty much everything else locally at a hardware store. They don't "look" as nice a a Plexiglas box sitting there but they work as good or better for performance.

I think you my be out of luck on the PCM for your model year.
