So does this sound right

Well that accelerometer I borrowed...I haven't gotten a chance to do a whole 1/4 mile yet...but
I did two 0-60 times...best being a 7.1 With an extra 150lbs in the car but it still makes me sad. I have no clue if this is way high or not.
My 60ft is ~ 2.3 which I guess is accurate for my car.

I'll keep this updated when I get 1/4 mile times from this gizmo.
