Hi guys. I'm not only new to these forums but am very much a car newbie. I didn't really have an interest in cars at all until I bought my first XR6 about a year ago (a 2004 Falcon BA). I recently (as in, one week ago) upgraded to a 2005 XR6 MkII Turbo and would like some advice on what exactly you think should be modified under the hood. As such, the car is pretty much stock everything apart from the wheels that I bought the day after buying it (not a fan of the stock ford wheels). The main thing I'm looking to improve is, of course, performance and if anyone has any tips to improve the fuel economy that would also be appreciated. Thanks guys, Matt
