Nice car! Ratio: your car probably has 4:10 ratio in the rear. If this is the case, you can go 65 no problem on the FWY. 3rd gear in the trans is like a straight 1:1, but being an auto slushbox, it isn't 100% efficient. Don't be afraid to wind the 2tc out in RPM. You will find that its happy place is high in the RPM. I am excited for you. I have 2 te27s in white.
