So I recently bought and put on my jb4 and the car ran great with no engine lights. When I put my vrsf down pipe I got the codes p1381, p0418. I don't know what I could of done to the car, when putting the down pipe on. That would make the car throw those codes. Does anyone have a solution for that. My one buddy said I might need to get a mhd tuner to plug in and flash my ecu.
