No I'm not burning oil and my sparks are fine. In idle it runs like **** but normal driving and in boost it runs perfect. I'm pretty sure I've fixed all the vaccum leaks already but I guess it can't hurt to check again. Last time it ended up being a loose bolt in the supercharger and a bad T, and all the lines looked good.
