Awesome car! well before you start modding best practice is to just make sure everything is running as it should be first. you could get MHD and the monitoring license to get some logs and see how everything is running. first thing that you will want to change is the charge pipe though if you are running good and decide to turn up the boost. after that its pretty much intercooler and downpipe. it is a slippery slope though and before you know it your slipping a big turbo on it haha.
