Yeah, getting a torque converter is the first step for an Auto. Stock, auto GT's go low 14's (like 14.2-14.4) with a good driver. 5-speeds can go high 13's to low 14's(13.8-14.2).
It was so funny when one of the dumbass general interest mags (C&D, R&T, Motortrend) pitted the auto GT against the Monte Carlo and the Stratus RT. Some how the best they could manage was like low 15's. I am convinced that they are terrible drivers, hence the reason I hate those publications. How hard is it to drive an auto GT???
