Hey guys I just got a CEL last night and i got it checked out today and seem to be my Cat. And I don't know how that is. I just got my JSP DP like last fall. And I'm running s JSP STG 3 software. So I got the CEL cleared and hopefully it doesn't come back on. What do you guys think is wrong ? Should I buy a new cat and get it installed or hit up JZW to get me s retune and have him clear the CEL with the new tune ? It wouldn't be worth it if it's the same stage tune. I rather upgrade to at least and TD04 and get a Stage 4 from JZW. What should I do guys ?
