Mechanical differences between V8 AU111 XLS and XR8?
I have an AU111 XLS V8 ute that I'd like to improve the performance of without spending too much money. It's my daily driver, and I was thinking that the local exhaust shop could improve the sound and it might even improve the fuel economy. This got me thinking.... what are the differences between the XLS and XR8 engines? Is the EECV computer identical?
