As the title states, my esp light is stuck on after I installed my stage 2 MAF based kit. I made sure all my connections are tight, and I checked my work as I went. The pump/solenoid worked when I used the boost mode and blew into the rubber hose. I have a new clutch that i have to baby for another 400 miles, so i dont know if the pump works with the controller in either mode while actually driving.
Anyways, after my first test drive with the kit in, I noticed that the ESP light came on, as well as the CEL.
