U0100 code after using SCT tuner

[James Cain]

So I got my SCT X4 with my custom tunes from 5 star tuning and followed the directions to program. Immediately after programming, I have a check engine light and it comes up as a U0100 code when checking it with my programmer. I do see a noticeable difference when driving the truck so it seems to have took the tune, but wondering if anyone else has had this issue after getting their 5 star tunes?

Never had a problem like that with mine. What if you go back to stock?

I just did mine this past week, same Tuner, and using 5 star tune. No issues with codes or anything else. Making about 18 lbs of boost over the stock 14ish.
Big difference in performance for me.

Well the code ended up going away after a couple days so just going to monitor it for now.

Hows it going with the tune? Still working well?
