It looks clean, alright. And that's online, as you can see. I've been reading that clean injection is unobtainable, but yesterday, I took a rusty one, fully tuned it and then left it in my garage.
Today, about to start a most wanted challenge with a friend, I called my personal vehicle... which turned out to be the injection as it had been the last car I used. Except now, it had lost the rust.
Good on me I guess. And for everyone who wants a clean injection, try doing that, maybe it'll work for you too.
