Shift Point

I'm a big fan of chassis dyno runs and doing all gears dyno pulls.
What you are going to find out is that your engine dyno numbers are going to be different
Than when you strap on your trans and rear end then your tire's.
Then factor in your different gear ratio's in your trans=torque multipyler.

When you do the all gear chassis pull you'll get your numbers for each gear and you can go from there to optimize you shifts.
