Hey guys I'm new to this site so I hope I'm posting in the right area, if not I apologize! Anyway I own a basically stock 04' WRX and I'm looking to install a new up pipe, down pipe, and an intake. This car is my DD so I don't want to do to much to it's engine at the moment. ANYWAY, when should I get a tune or do I even need a tune after I install these 3 parts? Since I've only owned this car for a few weeks I'm still new and learning about new things about it. So yes my question is when should I get a tune or do I even need a tune after these installs?
