I sit around 3.5 gs at about 75-80 mph 5th ....... what do i need to do to lower that? rear end ? tranny? If u have something to do this, lmk. I want better gas mileage on the interstate but still want my power on the lower end.

 

then drive slower and learn to pedal the car when cruising. I managed to get about 25-35 MPG on my 88T on the freeway cruising at 65 with the 3.73's.

 

Change the diff for a most desired ratio.

Select a transmission with a more desirable gear ration.

Spend money for custom gear ratio.

Use cruise control when possible

Tie helium ballons to your right foot to stay out of the throttle.

 

lol, i am using cruise, speed limit is 70mph at 70 im at 3gs. think ill just have to leave it alone. thanks for the help,(i still get around 27mph on hwy.)

 

27 mpg in a Z? what are you complaining about? Get a Civic if thats not good enough.

 

lol **** on civics, they are oil spills. sorry if that offends you in anyway.
