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


Here’s the picture

 

A few people have mentioned this happening to them. Check this thread out. https://www.clublexus.com/forums/is-...ine-power.html

 

well, you're gonna want to read the code first.

 

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.

 

That sounds good! I will give that a try, thank you!

 

just went over the threads, thanks for the help! I might take off the tune then go to the dealer
