So i got all my parts in today, and I was looking through the SCT manual and it lists the gear ratios, all of em except 3.90 Did i screw myself over? In my mod list to brenspeed i listed 3.90s so maybe can he tune it to include the 3.90s? Suggestions? Just load the 3.73 ratio since its closer than 4.10 or what? thanks
And no my parts havent been installed yet, waiting for brenspeed to email me the tune, gonna put all the parts on at once to get a massive jump in HP

the tune will recal the speedometer, without the tune your speedometer will read higher than it actually is, but nothing other than that.
