I just recieved my flash tuner for my f6 and going through he instructions it says I have to remove a couple of fuses ( fuel pump and another I forget which one). I just wanna hear from people who have used one before and would like to know if this is truely needed or can I get away without doing it?

No answer in months. Anyway, I don't have one but am getting a SCT soon and think you should follow the instructions to the T and don't deviate. Better to be safe than sorry. Probably no warranty anyway when using the tuner. Best to contact the manufacturer or the tuner you got it from.
