I have a 2010 6.7L Cummins 6-speed manual and the RaceME Ultra tuner.

I did the on-the-fly tuning update on the tuner with a mac book pro, and now it comes up with P0507 and P0506 idle higher than expected and idle lower than expected.

I think it has something to do with how the tuner was updated or the tuner itself, but no one can tell me anything, and there is absolutely nothing on google when you type the codes in.

Can anyone here shed some light on my problem, please, whether it be a tuner problem or some sensor?
