When i installed the jb4, i did a 25% e85 mix and the car ran great. After installing a new intake and charge pipe i tried 50%. Then car ran like crap. Kicked me to map 4, engine malfunction warning. Car drives great in normal driving, but horrible under WOT. So i figured too much e85. Drove car around and got fuel level down to almost a half tank and filled up with 93. Which shouldve put me back around 25% e85. Previously i was hitting 17psi. Now i can only get 12-14 out of it. Ive reset the map and moved the FOL down. Still wont make 17psi and acts funny under WOT. I can do the back end flash tomorrow but if it sounds like something else im all ears. What would make the car drop my boost level on map 5? Also a/f looks leaner than it was. Fuel trims maxing out so pulling boost?
