once I get a fuel curve that works with the WI. I basically have to start over with the fuel controller when using the WI. The first time I got my fuel curve "safe" without it @17psi I started turning up the boost and flipped it on. Major missfires, sounded like crap, lost a lot hp. Made some adjustments to the WI pressure and pump controller, disconnected the 2nd boost pressure sensor in my 95z to get rid of the annoying check engine light when I was boosting above 18 lbs.
