I have a 2018 gt pp1 with the torsen diff and 3.73 gears. Car is whippled and a manual. Im looking to lower my cruise rpms about 300ish on the freeway as im running about 2400-2500rpm at cruise now. I dont want to crush my accelerations but i know there is a little trade off. And for any who has done it would i be far off if i estimate $800 to have it done?
