Need help with something

1. Uploaded the Tune
2. Deleted the EGR
3. Replace the exhaust
4. Checked all Sensors

Still get the Exhaust fluid quality poor message and going near the Limp 4MPH mode.

Would you have any suggestions ?

Thanks

Dom

Contact your tuner

 

[Dom]

I have already contacted the tuner, but they do not seem to have an answer to the problem.
I do not know if by my insistence but they no longer answer me.

Is this on a 2018 ?

Maybe their delete tune isn't compatible with the new model year ?

 

[Turbowyo]

That is piss poor then.......he is leaving you stranded, you need a new dealer,what brand of tuner is it?

Its a 2017 Colorado
OZ Tuner

I know the 2017's had something different with them vs. the 2016's. DuramaxTuner and their counterpart out of Canada, MotorOps (who does emissions delete tuning), on their websites when ordering a tuner for our trucks, it asks if the truck is a 2016 or 2017. If it is a 2017, it adds an extra $80 for an EFI unlock authorization code.

Better be careful jacking with it. If the ecm detects emissions tampering it’ll lock out and you’re done playing. Only your tuner can fix this. Only thing you can do is double check what you’re supposed to disconnect
