[64speed]

I have the TKO600 with the .64 overdrive 3.70 gears and a 26 inch tall tire. The speed limit thru town is 30-35 at which of course I drive in 4th but on the side road home the speed limit is 50. Once I get some speed and RPM up I can shift to 5th at 45 mph and never lug the engine or lose my ability to gain speed. Engine rpm in 5th at 45-50 is just above idle. I feel like my rear gears are a little too deep to be ideal but it makes it really easy to take off and drive 1st is just a little short. When I went to the beach in March I put 22 gallons in the tank and drove 232 miles to the hotel (interstate 90%) and then drove around Myrtle Beach when I got there another 25-30 miles and I still had about 3 gallons. The TKO and the RTX gauges are the best upgrades to the car I have made.
