you don't need to per se but it's pretty darn important you do if you ask me

Not sure what gears are in there but I'd say shoot for something for 5.86 or in that area.

Where the light orange means better gas mile but less power, the middle means around factory specs, and the red is more power but less gas mileage.

That chart is not for an automatic trans.
