Well I took the car out tonight for the first time since I filled up with Toluene. Believe it or not the car ran much smoother(I swear, I'm not just making it up), BUT still don't feel as much of a performance gain as I normally do with 5-6 gallons of 100octane. I'm still going to VAG it to make sure I have no codes. But I think EF is right by saying I have a VAC leak, I think thats what's making that high pitch noise during cold start ups.

For those who were following last Thursdays post about the In n out chick here is an Updated and more on offtopic. lol<ul><li><a href="https://forums.audiworld.com/other/msgs/3043345.phtml">https://forums.audiworld.com/other/msgs/3043345.phtml</a></li></ul>
