by speed shifting do you mean holding the gas down and shifting ?? how often do you hit the rev limiter ???
are you burning any oil ?? Have you relocated the o2 sencors ??
ok im not burning any oil, no relocated 02 sensors and i dont hold the gas, by speed shifting im meaning shift as fast as you can when u hit redline, and i dont often hit the rev limiter and i do have a nismo intake but i doubt it would throw off the maf
