Default 2018 IS300 RWD check engine light

Hey everyone! This my first time making a thread with the forum.

So I Drive an 2018 IS300 FSport RWD, and 2 weeks back I decided to install an Ingen intake & VR tuned for the car. When I finish installing it nothing was wrong, it was plug and play. but earlier today while I was driving the check engine light came out, and it says reduced speed. Has this happened to anyone or does anyone have experience with similar situation? I’m very confused

You will want to remove the tune and see if the code returns. If it does, then take it to the dealer with the stock ECU files loaded.
If it doesn't return for a couple weeks, then reinstall the tune and see if it returns. If it does, then it could be related to the tune, in which case contact VR.
