Hi guys
So I know that everyone says you need a HPFP if you upgrade your turbo but I'm really looking to learn more about this. Most of what I've read suggests its absolutely necessary if you live in the USA due to their fuel quality. I'm wondering if anyone knows any real facts about why you would need it in Australia and does anyone have any experiences of what has happened in Oz without one.
Thanks heaps in advance :)
