7heavn, have you worked out what is up with your car and that time? Could the dyno be reading too high? How is the power made? Peaky or linear? I mean you are getting 1.7 60 ft's, so it really isn't lacking at the line. Is it running clean in the top end?
I just ran a few numbers on a calculator and came up with 11.88@114MPH, so the MPH is there, but the time is a bit out.
