Do you have one installed? I’ve followed the Mishimoto thread but it sounds like they are still tweaking their catch can to avoid the CEL faults. I’d be comforted to know they’ve finalized it to a point where the CEL codes no longer appear.A "catch can" will alleviate those worries. You know you want it, Resistance is Futile !
I am rooting for the turbo option. The math on the fuel savings seems to be a wash, so it’s more about power and range.
