I have a question for anyone running Ktuner with the Downpipe
I turned off the catalyst efficiency code, but I'm still getting a CEL for an emissions system problem. Error code is U301 and I can't find anything helpful when I search for information on it.
Has anyone had this same error code...
:bs: Sorry you guys have had to wait so long, it really is an excellent upgrade and is very well crafted but I would be just as upset having to wait 2 weeks longer than the rest of us.

let me know what I can do to improve the guide, also not sure if I posted in the right section
