Actually, the gears are stock. The Final Drive has been raised a bit (3.30 is stock, 3.60 is my number), which in turn shortens the gearing. Felt like it did what I wanted it to - didn't bog down when changing gears, and wasn't revved so high it was spinning tires everywhere. I honestly didn't spend much time with this tune...I didn't even get into individual gears with it, and a higher rear ARB than front is not normal for me in a RWD car. It didn't get fully worked over...just enough for it to do what I wanted it to at those short Snake tracks.
