No you’re not over informing at all.. I am a mechanical engineer and I already blew my brains out on this issue and I want to fully understand what could be wrong so thanks for everything!!

Your description and symptoms made me think of this video, especially considering you replaced the supercharger pulley. May be worth checking.

From: Under the car. As per normal.
I am getting code p0107 ever since we got the car and we put on the oem sc pulley. Before there was a 15% pulley installed and the car was mapped. Thanks for any advice. I was thinking of swapping back the pulley and then see if the code and dsc light will dissapear.
Just curious if you ever went back and did this.

I assume that’s RON octane… so about 95 AKI I think? What do you normally run?
