I was told the compression is 10.5 and the hp is 550. I am curious though about the injectors, are they big enough, as a relative point (I think) the fuel pressure is set at 62 psi, when I got the car it was some where between 75 & 80 psi. Unfortunatly I have been experiencing some minor probs which has prevented any performance tinkering.
