Halp. Out doing some pulls with a buddy of mine last night, after several the car started acting funny. 05 evo 8, full bolt on, cams, 775 injectors, evo 9 turbo. 400 to the wheels on 25-26 pounds. After our 5th or 6th pull we went one more and the car started shuttering hard. It felt like a very fast, violent spark blow out. Plugs are less than 2000 miles old, gapped at .022. It afr sensor is broke at the moment, but it smelled like a ton of gas wasn't getting burned. Held boost just fine, so not a boost leak. Any other ideas?
