Installed the fix from Apex this evening. Took about 5 minutes max. I know there is a debate on whether or not you will get more performance, but it sure feels like there is a bit of difference. Like 4k-7k rpm goes by like the wind. Everyone agrees the fix will improve gas milage, and so maybe its running better cause its not running so rich. now i need to change my oil to synthetic and plugs to something good.
