First off I'm a newb on your board here. Just want to say greetings to everyone. I am usually on an Accord board but I recently bought a MAZDA 3 5-door, and I must say I love it (bow) . I have one concern though and I have seen that Nathan G put this question out there but I saw no definite answer to it. I also got my M3 to 120 at which point the s*** was scared out of me when the speed limiter(or rev limiter not sure which it is. I've been told both names) kicked in. Needless to say I was kinda pissed (protest) because I had plenty of power left. So after all that my questions are: 1. Is that a speed limiter, rev limiter or governer. 2. How do you disable it or remove it. Any help would be appreciated.
