Interesting gear choice, why did you choose 4:11 gears over 3:73 or 3:55?Well I am most likely will be the the moron ... I just ordered 4.11 gears for my 17 mustang ecoboost... I have the NX2 turbo that fully kicks in around 3500 rpms... I use mine as a daily driver so I definitely will be the Guinea pig on this one. I will update later.
