When I installed a E303 in my car and drove it around,I revved it to what I thought was 7000 rpm's,then I read an article in Muscle Mustangs and Fast Fords that there is a 6250 rev-limiter in the car.
My first thought what does some magazine guy know about my car,if the factory tach said 7000 rpm then by god that motor just revved to 7000 rpm's.
Well I went and bought a Auto Meter tach that has 2 needles on it,one that moves and one that sits at the shift point. What a wake up call that was,I had one of my friends in the car with me and I say watch how high this E303 cam can rev........right about the time the tach hit 6200 the needle started shuttering,and I was so emberrassed,last time I did not believe what a magazine told me for awhile,they still once in awhile contradict themselves but some of that propoganda can be money saving.
Long story short,if you want to get around the rev-limiter you can buy an Extender,EPEC,PMS,or switch it out for DFI,I think DFI has changed their name but I think everyone knows what I am talking about.
