My VEC 2 is mounted under my hood..Its sweet how Heffner has it set up , he gave me two pre-programmed Cards. One is programmed for when I run race fuel and the other is for 91 OCT.
You just slip the card in and it adjusts the timing accordingly.
Absulutley.............you feel the difference.
I never dynoed before and after, but this I can tell you...........if K&N filter give an extra 10 HP, then the VEC1 must be closer to 20 HP. Just my :twocents:
