Okay so i have an A55 2007 tomos targa lx, that had about 3300 miles on it. I also still have the oil injection. I decided to put a biturbo on it, so i upjetted to a 60 jet and put on a high flow air filter. I was performing the first plug chop, and the plug looked fine nice and brown. Then as i was driving back home, my engine started losing power, studdered and went out. When i would try to start it up again, the engine would start up and sound nice, only to exert no power and studder out. Any help would be appreciated as i dont have much experience yet.
