downshifts need a bit more aggression and upshifts need some work. exterior is meh, but overall its not too bad I would give 3.5, but since I can't I give a 4
Nice mod, but it's not 100% perfect. The sound it's like 1500-2000 rpm high-pitched. About the delayed upshifting sound, check if you deactivated the "STREAM" on all audio clips on FMOD studio.
excessive rumble from the outside, almost feels like it is covering the sound of the engine itself. And the grumbling noises in the interior is terrible, why is it so loud and it is constantly on?
