I'm still fresh at this so please bare with me and correct me if I'm wrong or in the wrong forum. I'm trying to "sup" up my 2003 impala 3.4L V6. I've looked all over the web, asked around and still get the same answers. The only things I can do from what I am told is to get an aftermarket air intake, a high performance computer chip, dual exhaust ,electric turbocharger, and nitrios oxide, and engine swap.Any help would be appreciated.Thanks.
