I’m really bummed because I spent $1k because of the no CEL guarantee... yet I still got one, and I’m short $300 on the install.
I’m also open to ideas on how to get rid of the CEL. I’m seeing mixed reviews on the O2 spacer (L and straight) on the B58. Some say it works, other say it doesn’t.  |
Please update soon. Mine hasn't been on for more than 100 miles and now i'm worried.
Please update if you get the chance to check the code. I too paid the steep price for the no cel gaurantee, I could do the same with a cheaper downpipe and O2 spacer.
