When you are on it under boost near the top of the RPMs does power nose over and your check engine light flicker or come on?
Or is it after you run it out under boost and near the top of the RPMs then shift that it comes on?

the light comes on under boost and then it will start missing. the air fuel gauge doesnt read lean until after the check engine light is on and after it starts missing. the 30s i got leak. i got to clean them out some time just havent gotten around to it. dont know if it was my fault or not but im not trippin.
