Ok Gary, if the shift points are better for your combination it will help.
The better effective gear ratio will help.
The loss of 200 lbs will help approx. 2 tenths.
The Accel system won't make any difference if your stock system was in good
condition. Been there, done that!
So, if your weather conditions and traction are the same next time you
should see a gain of about 2-3 tenths. If they're better you could see
more, if worse you'll see less. Also, where you stage at the line can make
up to a tenth of a second difference. Difficult to explain but just
experiment. In short, creep from the pre-stage beam to the staged beam and
stop the instant it lights.
