Tune ?

[Dieselroller]

Got your extreme street tune on my sct and now my truck is running rough when cold and it threw a ficm operation code. Any ideas on what it could be?

When you say that it is cold out, what temperature? Did you try returning to sock to see if it went away? I hate to be the bearer of bad news, but I think that your FICM is on its way out. A weak FICM will be more noticeable in the colder weather. I hope this helps.

Yea. Not that cold. I want one that's been tuned anyway

If you know anyone with a 6.0 and a good FICM you can swap it to verify first.

The Xtreme tunes can be a little rougher on cold starts, but it shouldn't be too bad. Just a light puff of smoke and possible a little shaking. It really depends on if there are any injectors sticking when cold and the factory FICM flash and health of it.

I can try to tweak if there's any issues and I always recommend RevX on your oil change in the HEUI 7.3L and 6.0L trucks.


Thanks.
