Hey guys. My 2015 Nismo with 37,000 miles was tuned for a long time and had two step. Long story short I had check engine lights for the mass airflow sensors and a huge loss of power/acceleration issues. I cleaned and even swapped new MAF along with the throttle bodies, and it did nothing.

Today I bought an UpRev cable, removed the tune back to stock and the CEL is gone and the car runs good again. However my OBD2 scanner is picking up 1 code only and that’s the U1024. It doesn’t show in the dash (yet)

Will this code go away on its own? Shall I be worried? I’m confident I did everything right and the car is now 100% stock again. Any input will be grateful. Thanks
