I'm going to start with a downpipe for now until more research and test are done with the tunes before jumping in. I just might wait until warranty period to be over first. Not in a rush to boost high horsepower on this car. It has plenty for my daily drive already.
I've also tried unplugging the cameras after a full charge and the lights still come on. I will have to see when the dealer swap the battery to see if it will happen again. It's still under warranty so it will be covered for now.
The installer said the separate battery is not needed as it has the device to monitor the battery from hitting the low. I also charged it back up but the light still on.
I got this same issue with my supra. The dealer is ordering a new battery for me. I tried charging the battery and the charger shows 100% fully charged but it still show to replace the battery.
I'm getting a quote now for a set of Stance SF07. They quoted for a set of 20X10 +34 front and 20X11 +28 rear. Are those sizing too much for the supra? It will stick out 20mm front and 18mm rear.
